As somebody with own InnerSource experiences, you can share your experience with the authors.
 
-4. **Contribute a new pattern.** A key contribution you can make is to document an InnerSource best practice you experienced or know about. We defined different maturity levels for the contents in this repository: First time contributors should aim for maturity levels `1: initial` (for unstructured experience reports or what we call donuts - patterns with missing pieces) and `2: structured` (for best practices adhering to the patterns format and following basic writing style conventions). Our [Contributor Handbook](meta/contributor-handbook.md) discusses all this in more detail. You don't feel ready yet to contribute a new pattern? Please start a discussion by  [creating an issue](https://github.com/InnerSourceCommons/InnerSourcePatterns/issues/new).
