 The best way to get started with a contribution is to start a dialog with us. Sometimes features will be under development or out of scope for this library and it's best to check before starting work on contribution, especially for large work items.
 
 ## Pull requests
-If you are making documentation changes, feel free to submit a pull request against the **main** branch. All other pull requests should be submitted against the **dev** branch or a specific feature branch. The master branch is intended to represent the code released in the most-recent composer package.
