+# How to Contribute to Avalanche
+
+## Setup
+
+To start developing on AvalancheGo, you'll need a few things installed.
+
+- Golang version >= 1.22.8
+- gcc
+- g++
+
+## Issues
+
+### Security
+
+- Do not open up a GitHub issue if it relates to a security vulnerability in AvalancheGo, and instead refer to our [security policy](./SECURITY.md).
+
+### Did you fix whitespace, format code, or make a purely cosmetic patch?
+
+- Changes from the community that are cosmetic in nature and do not add anything substantial to the stability, functionality, or testability of `avalanchego` will generally not be accepted.
+
+### Making an Issue
+
+- Check that the issue you're filing doesn't already exist by searching under [issues](https://github.com/ava-labs/avalanchego/issues).
+- If you're unable to find an open issue addressing the problem, [open a new one](https://github.com/ava-labs/avalanchego/issues/new/choose). Be sure to include a *title and clear description* with as much relevant information as possible.
+
+## Features
+
+- If you want to start a discussion about the development of a new feature or the modification of an existing one, start a thread under GitHub [discussions](https://github.com/ava-labs/avalanchego/discussions/categories/ideas).
+- Post a thread about your idea and why it should be added to AvalancheGo.
+- Don't start working on a pull request until you've received positive feedback from the maintainers.
+
+## Pull Request Guidelines
+
+- Open a new GitHub pull request containing your changes.
+- Ensure the PR description clearly describes the problem and solution. Include the relevant issue number if applicable.
+- The PR should be opened against the `master` branch.
+- If your PR isn't ready to be reviewed just yet, you can open it as a draft to collect early feedback on your changes.
+- Once the PR is ready for review, mark it as ready-for-review and request review from one of the maintainers.
+
+### Autogenerated code
+
+- Any changes to protobuf message types require that protobuf files are regenerated.
+
+```sh
+./scripts/protobuf_codegen.sh
+```
+
+- To add or remove an interface that needs a corresponding mock generated, add it to the mock file [here](./scripts/mocks.mockgen.txt). You can regenerate the mocks by running the following script.
+
+```sh
+./scripts/mock.gen.sh
+```
+
+### Testing
+
+#### Local
+
+- Build the avalanchego binary
+
+```sh
+./scripts/build.sh
+```
+
+- Run unit tests
+
+```sh
+./scripts/build_test.sh
+```
+
+- Run the linter
+
+```sh
+./scripts/lint.sh
+```
+
+### Continuous Integration (CI)
+
+- Pull requests will generally not be approved or merged unless they pass CI.
+
+## Other
+
+### Do you have questions about the source code?
+
+- Ask any question about AvalancheGo under GitHub [discussions](https://github.com/ava-labs/avalanchego/discussions/categories/q-a).
+
+### Do you want to contribute to the Avalanche documentation?
+
+- Please check out the `avalanche-docs` repository [here](https://github.com/ava-labs/avalanche-docs).
