+* Avoid including irellevant whitespace or formatting changes.
+* Comment your code.

+
+## New features
+xNode aims to be simple and extendible, not trying to fix all of Unity's shortcomings.
+
+If your feature aims to cover something not related to editing nodes, it generally won't be accepted. If in doubt, ask on the Discord channel.
+
+## Coding conventions
+Skim through the code and you'll get the hang of it quickly.
+* Methods, Types and properties PascalCase
+* Variables camelCase
+* Public methods XML commented
