-# Development
-## Versioning
-This project uses the `x.y.z-releaseType` schema for releases.  
-Development builds are tagged as `x.y.z-SNAPSHOT` and sometimes pushed to the snapshots Maven repository.  
-Stable builds are tagged as `x.y.z` and always pushed to the releases Maven repository, by promoting the build on
-[Drone](https://drone.beatrice.wtf/). Currently, promoting stable builds is a manual process.
