 ### Submitting a pull request
 
 - Non-trivial changes are often best discussed in an issue first, to prevent you from doing unnecessary work.
+- For ambitious tasks, you should try to get your work in front of the community for feedback as soon as possible. Open a pull request as soon as you have done the minimum needed to demonstrate your idea. At this early stage, don't worry about making things perfect, or 100% complete. Add a [WIP] prefix to the title, and describe what you still need to do. This lets reviewers know not to nit-pick small details or point out improvements you already know you need to make. 
 - New features should be accompanied with tests and documentation.
 - Don't include unrelated changes.
 - Lint and test before submitting the pull request by running `$ npm test`.
