# PR Title
Be aware that we use the title to create changelog automatically and therefore only allow specific prefixes
- break: to indicate a breaking change, this supersedes any of the types
- feat: to indicate new features or checks
- fix: to indicate a bugfix or handling of edge cases of existing checks
- docs: to indicate an update to our documentation
- chore: to indicate adjustments to workflow files or dependency updates
- platform: to indicate a change needed for the platform
Additionally a scope is needs to be added to the prefix, which indicates the targeted framework, in doubt choose 'general'.
