Software Carpentry is an open source project,
and we welcome contributions of all kinds:
new lessons,
fixes to existing material,
bug reports,
and reviews of proposed changes are all equally welcome.

By contributing,
you are agreeing that Software Carpentry may redistribute your work under
[these licenses](LICENSE.html).

## Getting Started

1.  We use GitHub flow to manage changes,
    which is explained in the chapter [Contributing to a Project](http://git-scm.com/book/en/v2/GitHub-Contributing-to-a-Project)
    in Scott Chacon's book *Pro Git*.

2.  For our lessons,
    you should branch from and submit pull requests against the `gh-pages` branch.

3.  When editing lesson pages, you need only commit changes to the Markdown source files.

4.  If you're looking for things to work on,
    please see the current list of issues
    for [this repository](https://github.com/swcarpentry/lesson-template/issues),
    or for [http://software-carpentry.org/lessons.html](our other lessons).
    Comments on issues and reviews of pull requests are equally welcome.

## Other Resources

1.  This lesson is based on the template found at
    [https://github.com/swcarpentry/lesson-template](https://github.com/swcarpentry/lesson-template).
