+## Workflow
+This repo uses Gitflow as its branch management system. You can learn more about Gitflow [here](https://www.atlassian.com/git/tutorials/comparing-workflows#gitflow-workflow).
+A few quick tips:
+* All feature branches should be based on `develop` and have the format `feature/branch_name`.
+* Minor bug fixes should be based on `master` and have the format `hotfix/branch_name`.
