+# 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.

-# 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 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 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.
