 To contribute to Headscale you would need the lastest version of [Go](https://golang.org) and [Buf](https://buf.build)(Protobuf generator).
 
+### Code style
+
+To ensure we have some consistency with a growing number of contributes, this project has adopted linting and style/formatting rules:
+
+The **Go** code is linted with [`golangci-lint`](https://golangci-lint.run) and 
+formatted with [`golines`](https://github.com/segmentio/golines) (width 88) and 
+[`gofumpt`](https://github.com/mvdan/gofumpt).
+Please configure your editor to run the tools while developing and make sure to 
+run `make lint` and `make fmt` before committing any code.
+
+The **Proto** code is linted with [`buf`](https://docs.buf.build/lint/overview) and 
+formatted with [`clang-format`](https://clang.llvm.org/docs/ClangFormat.html).
+
+The **rest** (markdown, yaml, etc) is formatted with [`prettier`](https://prettier.io).
+
+Check out the `.golangci.yaml` and `Makefile` to see the specific configuration.
