It does no harm to provide +the same information in the pull request (if the pull request consists of a single commit, +the commit message will be added to the pull request automatically). + +* With few exceptions, it is mandatory to write a new test case that tests the feature. +The test case is needed to ensure that the features does not stop working in the future. + +* Update the [Documentation](https://github.com/erlang/otp/wiki/Documentation) to describe the feature. + +* Make sure that the new feature builds and works on all major platforms. Exceptions are features +that only makes sense one some platforms, for example the `win32reg` module for accessing the Windows registry. + +* Make sure that your feature does not break backward compatibility. In general, we only break backward +compatibility in major releases and only for a very good reason. Usually we first deprecate the +feature one or two releases beforehand. + +* In general, language changes/extensions require an +[EEP (Erlang Enhancement Proposal)](https://github.com/erlang/eep) to be written and approved before they +can be included in OTP. Major changes or new features in ERTS, Kernel, or STDLIB will need an EEP or at least +a discussion on the mailing list. + +## Before you submit your pull request + +* Make sure existing test cases don't fail. It is not necessary to run all tests (that would take many hours), +but you should at least run the tests for the application you have changed. +See [Running tests](https://github.com/erlang/otp/wiki/Running-tests). + +Make sure that your branch contains clean commits: + +* Don't make the first line in the commit message longer than 72 characters. +**Don't end the first line with a period.** + +* Follow the guidelines for [Writing good commit messages](https://github.com/erlang/otp/wiki/Writing-good-commit-messages). + +* Don't merge `maint` or `master` into your branch. Use `git rebase` if you need to resolve merge +conflicts or include the latest changes. + +* To make it possible to use the powerful `git bisect` command, make sure that each commit can be +compiled and that it works. + +* Check for unnecessary whitespace before committing with `git diff --check`. + +Check your coding style: + +* Make sure your changes follow the coding and indentation style of the code surrounding your changes. + +* Do not commit commented-out code or files that are no longer needed.
