 Tailscale is [a modern VPN](https://tailscale.com/) built on top of [Wireguard](https://www.wireguard.com/).

 1. We have nothing to do with Tailscale, or Tailscale Inc.
 2. The purpose of writing this was to learn how Tailscale works.
 
+## Contributing
+
+To contribute to Headscale you would need the lastest version of [Go](golang.org) and [Buf](https://buf.build)(Protobuf generator).
+
+### Install development tools
+
+- Go
+- Buf
+- Protobuf tools:
+
+```shell 
+make install-protobuf-plugins
+```
+
+### Testing and building
+
+Some parts of the project requires the generation of Go code from Protobuf (if changes is made in `proto/`) and it must be (re-)generated with:
+
+```shell
+make generate
+```
+**Note**: Please check in changes from `gen/` in a separate commit to make it easier to review.
+
+To run the tests:
+
+```shell
+make test
+```
+
+To build the program:
+
+```shell
+make build
+```
