+Release Procedure
+-----------------
+
+If you are preparing a release, ensure you have checked the following -
+
+- Update any remaining change logs
+    - These are currently documented both within the main readme and the plugin.xml files
+- Ensure all tests pass within IntelliJ
+- Use the generated JAR from Maven, and *not* IntelliJ's `prepare Module` operation
+    - This is to stop compiling against the incorrect JDK version
+- Upload to Jetbrain's plugin repository
+- Tag the release
+- Update version numbers, both within the plugin.xml and POM files
+- Relax
