-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including

-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,

-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-
-   END OF TERMS AND CONDITIONS

-   APPENDIX: How to apply the Apache License to your work.

+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+# MinIO Pull Request Guidelines
+
+These guidelines ensure high-quality commits in MinIO’s GitHub repositories, maintaining 
+a clear, valuable commit history for our open-source projects. They apply to all contributors, 
+fostering efficient reviews and robust code.
+
+## Why Pull Requests?
+
+Pull Requests (PRs) drive quality in MinIO’s codebase by:
+- Enabling peer review without pair programming.
+- Documenting changes for future reference.
+- Ensuring commits tell a clear story of development.
+
+**A poor commit lasts forever, even if code is refactored.**
+
+## Crafting a Quality PR
+
+A strong MinIO PR:
+- Delivers a complete, valuable change (feature, bug fix, or improvement).
+- Has a concise title (e.g., `[S3] Fix bucket policy parsing #1234`) and a summary with context, referencing issues (e.g., `#1234`).
+- Contains well-written, logical commits explaining *why* changes were made (e.g., “Add S3 bucket tagging support so that users can organize resources efficiently”).
+- Is small, focused, and easy to review—ideally one commit, unless multiple commits better narrate complex work.
+- Adheres to MinIO’s coding standards (e.g., Go style, error handling, testing).
+
+PRs must flow smoothly through review to reach production. Large PRs should be split into smaller, manageable ones.
+
+## Submitting PRs
+
+1. **Title and Summary**:
+   - Use a scannable title: `[Subsystem] Action Description #Issue` (e.g., `[IAM] Add role-based access control #567`).
+   - Include context in the summary: what changed, why, and any issue references.
+   - Use `[WIP]` for in-progress PRs to avoid premature merging or choose GitHub draft PRs.
+
+2. **Commits**:
+   - Write clear messages: what changed and why (e.g., “Refactor S3 API handler to reduce latency so that requests process 20% faster”).
+   - Rebase to tidy commits before submitting (e.g., `git rebase -i main` to squash typos or reword messages), unless multiple contributors worked on the branch.
+   - Keep PRs focused—one feature or fix. Split large changes into multiple PRs.
+
+3. **Testing**:
+   - Include unit tests for new functionality or bug fixes.
+   - Ensure existing tests pass (`make test`).
+   - Document testing steps in the PR summary if manual testing was performed.
+
+4. **Before Submitting**:
+   - Run `make verify` to check formatting, linting, and tests.
+   - Reference related issues (e.g., “Closes #1234”).
+   - Notify team members via GitHub `@mentions` if urgent or complex.
+
+## Reviewing PRs
+
+Reviewers ensure MinIO’s commit history remains a clear, reliable record. Responsibilities include:
+
+1. **Commit Quality**:
+   - Verify each commit explains *why* the change was made (e.g., “So that…”).
+   - Request rebasing if commits are unclear, redundant, or lack context (e.g., “Please squash typo fixes into the parent commit”).
+
+2. **Code Quality**:
+   - Check adherence to MinIO’s Go standards (e.g., error handling, documentation).
+   - Ensure tests cover new code and pass CI.
+   - Flag bugs or critical issues for immediate fixes; suggest non-blocking improvements as follow-up issues.
+
+3. **Flow**:
+   - Review promptly to avoid blocking progress.
+   - Balance quality and speed—minor issues can be addressed later via issues, not PR blocks.
+   - If unable to complete the review, tag another reviewer (e.g., `@username please take over`).
+
+4. **Shared Responsibility**:
+   - All MinIO contributors are reviewers. The first commenter on a PR owns the review unless they delegate.
+   - Multiple reviewers are encouraged for complex PRs.
+
+5. **No Self-Edits**:
+   - Don’t modify the PR directly (e.g., fixing bugs). Request changes from the submitter or create a follow-up PR.
+   - If you edit, you’re a collaborator, not a reviewer, and cannot merge.
+
+6. **Testing**:
+   - Assume the submitter tested the code. If testing is unclear, ask for details (e.g., “How was this tested?”).
+   - Reject untested PRs unless testing is infeasible, then assist with test setup.
+
+## Tips for Success
+
+- **Small PRs**: Easier to review, faster to merge. Split large changes logically.
+- **Clear Commits**: Use `git rebase -i` to refine history before submitting.
+- **Engage Early**: Discuss complex changes in issues or Slack (https://slack.min.io) before coding.
+- **Be Responsive**: Address reviewer feedback promptly to keep PRs moving.
+- **Learn from Reviews**: Use feedback to improve future contributions.
+
+## Resources

+- [Effective Commit Messages](https://mislav.net/2014/02/hidden-documentation/)
+- [GitHub PR Tips](https://github.com/blog/1943-how-to-write-the-perfect-pull-request)
+
+By following these guidelines, we ensure MinIO’s codebase remains high-quality, maintainable, and a joy to contribute to. Happy coding!

-# MinIO FIPS Builds
-
-MinIO creates FIPS builds using a patched version of the Go compiler (that uses BoringCrypto, from BoringSSL, which is [FIPS 140-2 validated](https://csrc.nist.gov/csrc/media/projects/cryptographic-module-validation-program/documents/security-policies/140sp2964.pdf)) published by the Golang Team [here](https://github.com/golang/go/tree/dev.boringcrypto/misc/boring).
-
-MinIO FIPS executables are available at <http://dl.min.io> - they are only published for `linux-amd64` architecture as binary files with the suffix `.fips`. We also publish corresponding container images to our official image repositories.
-
-We are not making any statements or representations about the suitability of this code or build in relation to the FIPS 140-2 standard. Interested users will have to evaluate for themselves whether this is useful for their own purposes.

-MinIO is a High Performance Object Storage released under GNU Affero General Public License v3.0. It is API compatible with Amazon S3 cloud storage service. Use MinIO to build high performance infrastructure for machine learning, analytics and application data workloads. To learn more about what MinIO is doing for AI storage, go to [AI storage documentation](https://min.io/solutions/object-storage-for-ai).
+MinIO is a high-performance, S3-compatible object storage solution released under the GNU AGPL v3.0 license.
+Designed for speed and scalability, it powers AI/ML, analytics, and data-intensive workloads with industry-leading performance.
 
-This README provides quickstart instructions on running MinIO on bare metal hardware, including container-based installations. For Kubernetes environments, use the [MinIO Kubernetes Operator](https://github.com/minio/operator/blob/master/README.md).
+- S3 API Compatible – Seamless integration with existing S3 tools
+- Built for AI & Analytics – Optimized for large-scale data pipelines
+- High Performance – Ideal for demanding storage workloads.
 
-## Container Installation
+This README provides instructions for building MinIO from source and deploying onto baremetal hardware.
+Use the [MinIO Documentation](https://github.com/minio/docs) project to build and host a local copy of the documentation.
 
-Use the following commands to run a standalone MinIO server as a container.
+## MinIO is Open Source Software
 
-Standalone MinIO servers are best suited for early development and evaluation. Certain features such as versioning, object locking, and bucket replication
-require distributed deploying MinIO with Erasure Coding. For extended development and production, deploy MinIO with Erasure Coding enabled - specifically,
-with a *minimum* of 4 drives per MinIO server. See [MinIO Erasure Code Overview](https://min.io/docs/minio/linux/operations/concepts/erasure-coding.html)
-for more complete documentation.
+We designed MinIO as Open Source software for the Open Source software community. We encourage the community to remix, redesign, and reshare MinIO under the terms of the AGPLv3 license.
 
-### Stable
+All usage of MinIO in your application stack requires validation against AGPLv3 obligations, which include but are not limited to the release of modified code to the community from which you have benefited. Any commercial/proprietary usage of the AGPLv3 software, including repackaging or reselling services/features, is done at your own risk.
 
-Run the following command to run the latest stable image of MinIO as a container using an ephemeral data volume:
+The AGPLv3 provides no obligation by any party to support, maintain, or warranty the original or any modified work.
+All support is provided on a best-effort basis through Github and our [Slack](https//slack.min.io) channel, and any member of the community is welcome to contribute and assist others in their usage of the software.
 
-```sh
-podman run -p 9000:9000 -p 9001:9001 \
-  quay.io/minio/minio server /data --console-address ":9001"
-```
+MinIO [AIStor](https://www.min.io/product/aistor) includes enterprise-grade support and licensing for workloads which require commercial or proprietary usage and production-level SLA/SLO-backed support. For more information, [reach out for a quote](https://min.io/pricing).
 
-The MinIO deployment starts using default root credentials `minioadmin:minioadmin`. You can test the deployment using the MinIO Console, an embedded
-object browser built into MinIO Server. Point a web browser running on the host machine to <http://127.0.0.1:9000> and log in with the
-root credentials. You can use the Browser to create buckets, upload objects, and browse the contents of the MinIO server.
+## Source-Only Distribution
 
-You can also connect using any S3-compatible tool, such as the MinIO Client `mc` commandline tool. See
-[Test using MinIO Client `mc`](#test-using-minio-client-mc) for more information on using the `mc` commandline tool. For application developers,
-see <https://min.io/docs/minio/linux/developers/minio-drivers.html> to view MinIO SDKs for supported languages.
+**Important:** The MinIO community edition is now distributed as source code only. We will no longer provide pre-compiled binary releases for the community version.
 
-> NOTE: To deploy MinIO on with persistent storage, you must map local persistent directories from the host OS to the container using the `podman -v` option. For example, `-v /mnt/data:/data` maps the host OS drive at `/mnt/data` to `/data` on the container.
+### Installing Latest MinIO Community Edition
 
-## macOS
+To use MinIO community edition, you have two options:
 
-Use the following commands to run a standalone MinIO server on macOS.
+1. **Install from source** using `go install github.com/minio/minio@latest` (recommended)
+2. **Build a Docker image** from the provided Dockerfile
 
-Standalone MinIO servers are best suited for early development and evaluation. Certain features such as versioning, object locking, and bucket replication require distributed deploying MinIO with Erasure Coding. For extended development and production, deploy MinIO with Erasure Coding enabled - specifically, with a *minimum* of 4 drives per MinIO server. See [MinIO Erasure Code Overview](https://min.io/docs/minio/linux/operations/concepts/erasure-coding.html) for more complete documentation.
+See the sections below for detailed instructions on each method.
 
-### Homebrew (recommended)
+### Legacy Binary Releases

-
-MinIO strongly recommends *against* using compiled-from-source MinIO servers for production environments.
-
-## Deployment Recommendations
-
-### Allow port access for Firewalls
-
-By default MinIO uses the port 9000 to listen for incoming connections. If your platform blocks the port by default, you may need to enable access to the port.
-
-### ufw
-
-For hosts with ufw enabled (Debian based distros), you can use `ufw` command to allow traffic to specific ports. Use below command to allow access to port 9000
-
-```sh
-ufw allow 9000
+```
+env GOOS=linux GOARCh=arm64 go build
 ```
 
-Below command enables all incoming traffic to ports ranging from 9000 to 9010.
+Start MinIO by running `minio server PATH` where `PATH` is any empty folder on your local filesystem.
+
+The MinIO deployment starts using default root credentials `minioadmin:minioadmin`.
+You can test the deployment using the MinIO Console, an embedded web-based object browser built into MinIO Server.
+Point a web browser running on the host machine to <http://127.0.0.1:9000> and log in with the root credentials.
+You can use the Browser to create buckets, upload objects, and browse the contents of the MinIO server.
+
+You can also connect using any S3-compatible tool, such as the MinIO Client `mc` commandline tool:
 
 ```sh
-ufw allow 9000:9010/tcp
+mc alias set local http://localhost:9000 minioadmin minioadmin
+mc admin info local
 ```
 
-### firewall-cmd
+See [Test using MinIO Client `mc`](#test-using-minio-client-mc) for more information on using the `mc` commandline tool.
+For application developers, see <https://docs.min.io/enterprise/aistor-object-store/developers/sdk/> to view MinIO SDKs for supported languages.
 
-For hosts with firewall-cmd enabled (CentOS), you can use `firewall-cmd` command to allow traffic to specific ports. Use below commands to allow access to port 9000
+> [!NOTE]
+> Production environments using compiled-from-source MinIO binaries do so at their own risk.
+> The AGPLv3 license provides no warranties nor liabilites for any such usage.
+
+## Build Docker Image
+
+You can use the `docker build .` command to build a Docker image on your local host machine.
+You must first [build MinIO](#install-from-source) and ensure the `minio` binary exists in the project root.
+
+The following command builds the Docker image using the default `Dockerfile` in the root project directory with the repository and image tag `myminio:minio`
 
 ```sh
-firewall-cmd --get-active-zones
+docker build -t myminio:minio .
 ```
 
-This command gets the active zone(s). Now, apply port rules to the relevant zones returned above. For example if the zone is `public`, use
+Use `docker image ls` to confirm the image exists in your local repository.
+You can run the server using standard Docker invocation:
 
 ```sh
-firewall-cmd --zone=public --add-port=9000/tcp --permanent
+docker run -p 9000:9000 -p 9001:9001 myminio:minio server /tmp/minio --console-address :9001
 ```
 
-Note that `permanent` makes sure the rules are persistent across firewall start, restart or reload. Finally reload the firewall for changes to take effect.
+Complete documentation for building Docker containers, managing custom images, or loading images into orchestration platforms is out of scope for this documentation.
+You can modify the `Dockerfile` and `dockerscripts/docker-entrypoint.sh` as-needed to reflect your specific image requirements.
 
-```sh
-firewall-cmd --reload
-```
+See the [MinIO Container](https://docs.min.io/community/minio-object-store/operations/deployments/baremetal-deploy-minio-as-a-container.html#deploy-minio-container) documentation for more guidance on running MinIO within a Container image.
 
-### iptables
+## Install using Helm Charts
 
-For hosts with iptables enabled (RHEL, CentOS, etc), you can use `iptables` command to enable all traffic coming to specific ports. Use below command to allow
-access to port 9000
+There are two paths for installing MinIO onto Kubernetes infrastructure:
 
-```sh
-iptables -A INPUT -p tcp --dport 9000 -j ACCEPT
-service iptables restart
-```
+- Use the [MinIO Operator](https://github.com/minio/operator)
+- Use the community-maintained [Helm charts](https://github.com/minio/minio/tree/master/helm/minio)
 
-Below command enables all incoming traffic to ports ranging from 9000 to 9010.
-
-```sh
-iptables -A INPUT -p tcp --dport 9000:9010 -j ACCEPT
-service iptables restart
-```
+See the [MinIO Documentation](https://docs.min.io/community/minio-object-store/operations/deployments/kubernetes.html) for guidance on deploying using the Operator.
+The Community Helm chart has instructions in the folder-level README.
 
 ## Test MinIO Connectivity
 
 ### Test using MinIO Console
 
-MinIO Server comes with an embedded web based object browser. Point your web browser to <http://127.0.0.1:9000> to ensure your server has started successfully.

+> [!NOTE]
+> MinIO runs console on random port by default, if you wish to choose a specific port use `--console-address` to pick a specific interface and port.
 
-### Things to consider
+### Test using MinIO Client `mc`
 
-MinIO redirects browser access requests to the configured server port (i.e. `127.0.0.1:9000`) to the configured Console port. MinIO uses the hostname or IP address specified in the request when building the redirect URL. The URL and port *must* be accessible by the client for the redirection to work.
+`mc` provides a modern alternative to UNIX commands like ls, cat, cp, mirror, diff etc. It supports filesystems and Amazon S3 compatible cloud storage services.
 
-For deployments behind a load balancer, proxy, or ingress rule where the MinIO host IP address or port is not public, use the `MINIO_BROWSER_REDIRECT_URL` environment variable to specify the external hostname for the redirect. The LB/Proxy must have rules for directing traffic to the Console port specifically.
-
-For example, consider a MinIO deployment behind a proxy `https://minio.example.net`, `https://console.minio.example.net` with rules for forwarding traffic on port :9000 and :9001 to MinIO and the MinIO Console respectively on the internal network. Set `MINIO_BROWSER_REDIRECT_URL` to `https://console.minio.example.net` to ensure the browser receives a valid reachable URL.

-## Test using MinIO Client `mc`
-
-`mc` provides a modern alternative to UNIX commands like ls, cat, cp, mirror, diff etc. It supports filesystems and Amazon S3 compatible cloud storage services. Follow the MinIO Client [Quickstart Guide](https://min.io/docs/minio/linux/reference/minio-mc.html#quickstart) for further instructions.
-
-## Upgrading MinIO
-
-Upgrades require zero downtime in MinIO, all upgrades are non-disruptive, all transactions on MinIO are atomic. So upgrading all the servers simultaneously is the recommended way to upgrade MinIO.
-
-> NOTE: requires internet access to update directly from <https://dl.min.io>, optionally you can host any mirrors at <https://my-artifactory.example.com/minio/>
-
-- For deployments that installed the MinIO server binary by hand, use [`mc admin update`](https://min.io/docs/minio/linux/reference/minio-mc-admin/mc-admin-update.html)
+The following commands set a local alias, validate the server information, create a bucket, copy data to that bucket, and list the contents of the bucket.
 
 ```sh
-mc admin update <minio alias, e.g., myminio>
+mc alias set local http://localhost:9000 minioadmin minioadmin
+mc admin info
+mc mb data
+mc cp ~/Downloads/mydata data/
+mc ls data/
 ```
 
-- For deployments without external internet access (e.g. airgapped environments), download the binary from <https://dl.min.io> and replace the existing MinIO binary let's say for example `/opt/bin/minio`, apply executable permissions `chmod +x /opt/bin/minio` and proceed to perform `mc admin service restart alias/`.
-
-- For installations using Systemd MinIO service, upgrade via RPM/DEB packages **parallelly** on all servers or replace the binary lets say `/opt/bin/minio` on all nodes, apply executable permissions `chmod +x /opt/bin/minio` and process to perform `mc admin service restart alias/`.
-
-### Upgrade Checklist
-
-- Test all upgrades in a lower environment (DEV, QA, UAT) before applying to production. Performing blind upgrades in production environments carries significant risk.
-- Read the release notes for MinIO *before* performing any upgrade, there is no forced requirement to upgrade to latest release upon every release. Some release may not be relevant to your setup, avoid upgrading production environments unnecessarily.
-- If you plan to use `mc admin update`, MinIO process must have write access to the parent directory where the binary is present on the host system.
-- `mc admin update` is not supported and should be avoided in kubernetes/container environments, please upgrade containers by upgrading relevant container images.
-- **We do not recommend upgrading one MinIO server at a time, the product is designed to support parallel upgrades please follow our recommended guidelines.**
+Follow the MinIO Client [Quickstart Guide](https://docs.min.io/community/minio-object-store/reference/minio-mc.html#quickstart) for further instructions.
