+First off. You are awesome. Thanks for wanting to help contribute to the JSketcher project. 
+
+To make things easier to manage we have some guidelines that will help to keep the codebase clean and tidy. 
+
+1. No merge commits. Everything should be rebased on top of the main branch. History should be one line/linear
+2. No unnecessary formatting/prettifiyng. Only for the neighborhood of the actual change.
+3. Indent is always 2 spaces. 
+4. Execute  ```npm run before-main-branch-merge``` to statically check and lint the code.
