go-ethereum/CONTRIBUTING.md

If you'd like to contribute to go-ethereum please fork, fix, commit and send a pull request. Commits who do not comply with the coding standards are ignored (use gofmt!). If you send pull requests make absolute sure that you commit on the develop branch and that you do not merge to master. Commits that are directly based on master are simply ignored.

See Developers' Guide for more details on configuring your environment, testing, and dependency management.
