+## Releasing
+
+* GitHub Releases automatically result in a deployment to GitHub Packages
+* Maven Central releases happen manually 
+  * This can only be done by @lopcode
+  * And only after a GitHub Release is made
+  * Run `./publish_release_to_maven_central.sh <version matching github release version>`
