+## Contribution workflow
+
+This is a rough outline of how to prepare a contribution:
+
+- Create a topic branch from where you want to base your work (branched from main).
+- Make commits of logical units.
+- Push your changes to a topic branch in your fork of the repository.
+- Submit a pull request to the original repository. It will be reviewed in a timely manner.
+
+### Pull Requests
+
+A pull request should address a single issue, feature or bug. For example, lets say you've written code that fixes two issues. That's great! However, you should submit two small pull requests, one for each issue as opposed to combining them into a single larger pull request. In general the size of the pull request should be kept small in order to make it easy for a reviewer to understand, and to minimize risks from integrating many changes at the same time. For example, if you are working on a large feature you should break it into several smaller PRs by implementing the feature as changes to several packages and submitting a separate pull request for each one.
+
+Code submitted in pull requests must be properly documented, formatted and tested in order to be approved and merged. The following guidelines describe the things a reviewer will look for when they evaluate your pull request. Here's a tip. If your reviewer doesn't understand what the code is doing, they won't approve the pull request. Strive to make code clear and well documented. If possible, request a reviewer that has some context on the PR.
