 # Style Guide
-The style is loosely based on [PEP8][1].
+Use the LSP plugin (search for it on Package Control) together with the
+python-language-server when you make changes to this plugin. You can install
+python-language-server with pip3. When you're done with the changes, format
+the document. Please trim whitespace and make sure views end with an empty line.
