 ## Pull Requests
 Try to keep your pull requests relevant, neat, and manageable. If you are adding multiple features, split them into separate PRs.
-* Avoid including irellevant whitespace or formatting changes.
-* Comment your code.
-* Spell check your code / comments
-* Use consistent formatting
+These are the main points to follow:
+
+1) Use formatting which is consistent with the rest of xNode base (see below)
+2) Keep _one feature_ per PR (see below)
+3) xNode aims to be compatible with C# 4.x, do not use new language features
+4) Avoid including irellevant whitespace or formatting changes
+5) Comment your code
+6) Spell check your code / comments
+7) Use concrete types, not *var*
+8) Use english language
 
 ## New features
 xNode aims to be simple and extendible, not trying to fix all of Unity's shortcomings.
 
+Approved changes might be rejected if bundled with rejected changes, so keep PRs as separate as possible.
+
 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.
