We welcome contributions from anyone on the internet, and are grateful for even the smallest of fixes!

## Contributing to the Geth source code {#contributing-to-source-code}

If you'd like to contribute to the Geth source code, please fork the [GitHub repository](https://github.com/ethereum/go-ethereum), fix, commit and send a pull request for the maintainers to review and merge into the main code base. If you wish to submit more complex changes though, please check up with the core devs first on our Discord Server to ensure those changes are in line with the general philosophy of the project and/or get some early feedback which can make both your efforts much lighter as well as our review and merge procedures quick and simple.

Please make sure your contributions adhere to our coding guidelines:

- Code must adhere to the official Go formatting guidelines (i.e. uses gofmt).
- Code must be documented adhering to the official Go commentary guidelines.
- Pull requests need to be based on and opened against the master branch.
- Commit messages should be prefixed with the package(s) they modify.
  E.g. "eth, rpc: make trace configs optional"

Pull requests generally need to be based on and opened against the `master` branch, unless by explicit agreement because the work is contributing to some more complex feature branch.

All pull requests will be reviewed according to the [Code Review guidelines](/docs/developers/geth-developer/code-review-guidelines).

We encourage an early pull request approach, meaning pull requests are created as early as possible even without the completed fix/feature. This will let core devs and other volunteers know you picked up an issue. These early PRs should indicate 'in progress' status.

## Contributing to the Geth website {#contributing-to-website}

The Geth website is hosted separately from Geth itself. The contribution guidelines are the same. Please check out the [website repository](https://github.com/ethereum/geth-website) and raise pull requests for the maintainers to review and merge.
