 ### Contributor's Guide
 
-This project follows the [![ColPrac: Contributor's Guide on Collaborative Practices for Community Packages](https://img.shields.io/badge/ColPrac-Contributor%27s%20Guide-blueviolet)](https://colprac.sciml.ai/), apart from the following slight variation:
-
-  - The master branch contains the most recent release at any point in time. All non-breaking changes (bug fixes etc.) are merged directly into master and a new patch version is released immediately.
-  - A separate dev branch contains all breaking changes, and is merged into master when a minor version release happens.
-
-For instance, suppose we are currently on version 0.13.5.
-
-  - If someone produces a bug fix, it is merged directly into master and bumps the version to 0.13.6. This change is also merged into dev so that it remains up-to-date with master.
-  - If someone is working on a new feature that is not breaking (performance-related, fancy new syntax that is backwards-compatible etc.), the same happens.
-  - New breaking changes are merged into dev until a release is ready to go, at which point dev is merged into master and version 0.14 is released.
