# Contributing to Maxscale
## Prerequisites
Basically, in order for us to be able to accept a contribution, it must be
licensed under [BSD-new](http://en.wikipedia.org/wiki/BSD_licenses). Upon
request, we can also provide a _contributor agreement_ for you to sign.
When you submit a pull request, add the following comment to your pull request.
> I am contributing the new code of the whole pull request, including one or
several files that are either new files or modified ones, under the BSD-new
license.
Without this comment, the pull request will not be accepted.
## Practicalities
* Please ensure that your pull-request has been made against the correct
branch. For bug fixes or minor improvements, use the default branch (at the
time of writing `2.1`). For new features, use the `develop` branch.
* Please ensure that your code follows our [Coding Style](https://github.com/mariadb-corporation/MaxScale/wiki/Coding-Style-and-Guidelines).
All new code should be formatted with the
[Astyle configuration](https://github.com/mariadb-corporation/MaxScale/wiki/Coding-Style-and-Guidelines#tldr)
provided with the MaxScale source code.
