Acceptance Criteria
- https://github.com/camunda/camunda-bpm-platform/blob/master/CONTRIBUTING.md is overhauled
- Relevant other repositories link to this contribution guide (so that we have it in one place)
Concrete things we can do:
- Reduce explanation of commit message guidelines
- Link to code style and testing best practices in dev docs
- Describe how to build the platform
- Create a checklist of things a contributor should do (limited to the necessities so that it is not overwhelming)
- Table of content at the beginning of the page
