+# Contribution Rules
+There are some simple rules that everyone should follow:
+
+### Do not commit files from bulid folder
+> I usually have horrible merge conflicts when I upload the build version that take me too much time to solve, but I want to keep the build version in the repo, so I guess it would be better if only one of us does the built, which would be me.
+> https://github.com/jagenjo/litegraph.js/pull/155#issuecomment-656602861
+Those files will be updated by owner.

 - Graphs can be executed in NodeJS
 - Highly customizable nodes (color, shape, slots vertical or horizontal, widgets, custom rendering)
 - Easy to integrate in any JS application (one single file, no dependencies)
+- Typescript support
 
 ## Nodes provided
 Although it is easy to create new node types, LiteGraph comes with some default nodes that could be useful for many cases:
