+1. Code and commit!
+
+   Here's a quick checklist for ensuring a good pull request:
+
+   - Only touch the minimal amount of files possible while still accomplishing the goal.
+   - Ensure all indentation is done as 4-spaces and your editor is set to unix line endings.
+   - The code matches PEP8 style guides. If you cloned the repo you can run `pycodestyle .`
+   - Keep commit messages clean and descriptive.
+     If the PR is accepted it will get 'Squashed' into a single commit before merging, the commit messages will be used to generate the Merge commit message.
 
-   Here's a quick checklist for ensuring a good diff:
+1. Add tests.
 
-   - The diff touches the minimal amount of files possible while still fufilling the purpose of the diff
-   - The diff uses Unix line endings
-   - The diff adheres to our PEP8 style guides. If you've cloned the repo you can run `pycodestyle .`
+   All of our tests live under the `test/` folder in the repository.  
+   We use `unittest` and the built-in test runner `python setup.py test`.  
+   If a test needs a static file, like a twb/twbx, it should live under `test/assets/`
 
-1. Add Tests
+1. Update the documentation.
 
-1. Update Documentation
+   Our documentation is written in markdown and built with Jekyll on Github Pages. All of the documentation source files can be found in `docs/docs`.
 
-   Our documentation is written in markdown and built with [Mkdocs](http://www.mkdocs.org). More information on how to update and build the docs can be found [here](#updating-documentation)
+   When adding a new feature or improving existing functionality we may ask that you update the documentation along with your code.
+
+   If you are just making a PR for documentation updates (adding new docs, fixing typos, improving wording) the easiest method is to use the built in `Edit this file` in the Github UI
 
-1. Run the tests again and make sure they pass!
+1. Submit to your fork.
 
-1. Submit to your fork
+1. Make a PR as described [here](https://help.github.com/articles/creating-a-pull-request-from-a-fork/) against the 'development' branch.
 
-1. Submit a PR
+1. Wait for a review and address any feedback.
+   While we try and stay on top of all issues and PRs it might take a few days for someone to respond. Politely pinging the PR after a few days with no response is OK, we'll try and respond with a timeline as soon as we are able.
 
-1. Wait for a review, and address any feedback.
+1. That's it! When the PR has received :rocket:'s from members of the core team they will merge the PR
