+# How to contribute
+
+We welcome contributions from external contributors, and this document
+describes how to merge code changes into this alchemtest. 
+
+If you want to **contribute a new test files** then please also read the
+ [Contributing new data sets](https://alchemtest.readthedocs.io/en/latest/contributing.html)
+chapter in the documentation.
+
+
+## Getting Started
+
+* Make sure you have a [GitHub account](https://github.com/signup/free).
+* [Fork](https://help.github.com/articles/fork-a-repo/) this repository on GitHub.
+* On your local machine,
+  [clone](https://help.github.com/articles/cloning-a-repository/) your fork of
+  the repository.
+
+## Making Changes
+
+* Add some really awesome code to your local fork.  It's usually a [good
+  idea](http://blog.jasonmeridth.com/posts/do-not-issue-pull-requests-from-your-master-branch/)
+  to make changes on a
+  [branch](https://help.github.com/articles/creating-and-deleting-branches-within-your-repository/)
+  with the branch name relating to the feature you are going to add.
+* When you are ready for others to examine and comment on your new feature,
+  navigate to your fork of alchemtest on GitHub and open a [pull
+  request](https://help.github.com/articles/using-pull-requests/) (PR). Note that
+  after you launch a PR from one of your fork's branches, all
+  subsequent commits to that branch will be added to the open pull request
+  automatically.  Each commit added to the PR will be validated for
+  mergability, compilation and test suite compliance; the results of these tests
+  will be visible on the PR page.
+* If you're providing a new feature, you must add test cases and documentation.
+* When the code is ready to go, make sure you run the test suite using pytest.
+* When you're ready to be considered for merging, check the "Ready to go"
+  box on the PR page to let the alchemtest devs know that the changes are complete.
+  The code will not be merged until this box is checked, the continuous
+  integration returns checkmarks,
+  and multiple core developers give "Approved" reviews.
