# Contributor Guidelines
Flask-Login is open source and will happily consider pull requests with bugfixes, documentation improvements, and ocassionally new features. Note that major changes will generally not be accepted.
Before you submit an issue or pull request, please read the following guidlines.
## Submitting Issues
Before you submit a new issue, **please review the [CHANGES](https://github.com/maxcountryman/flask-login/blob/master/CHANGES) document**. This is where you will find all major changes, including breaking changes, which may be causing your issue.
Do not open a new issue before reading through CHANGES thoroughly and reviewing other open and closed issues. Duplicate issues will be closed and locked. Please do not open issues related to release deadlines: we will get to it when we can and in the meantime you are free to issue your own releases however you like.
Issues should relate to specific bugs or feature requests. If this doesn't fit the profile, then please don't open an issue.
## Submitting a Pull Request
If you'd like to submit PR, please make sure that all tests pass prior to submission. The README contains further instructions.
