I added a little manual here - https://github.com/dvcrn/proton/blob/master/MANUAL.md. Currently it only covers the .proton file and how to set up proton through it. What are other things that could go in here?

If you have ideas, post them here: https://github.com/dvcrn/proton/issues/228

Some ideas would be: - Explain editor navigation, jumping between panes, etc - Explain how to use the different input modes (vim-mode, vim-mode-plus, emacs, default) - Explain the concept of ,, syntax specific leader
