From kickstarter

    TODO: The very first thing you should do is to run the command `:Tutor` in Neovim.

    If you don't know anything about Lua, I recommend taking some time to read through
    a guide. One possible example which will only take 10-15 minutes:
      - https://learnxinyminutes.com/docs/lua/

    After understanding a bit more about Lua, you can use `:help lua-guide` as a
    reference for how Neovim integrates Lua.
    - :help lua-guide
    - (or HTML version): https://neovim.io/doc/user/lua-guide.html

    MOST IMPORTANTLY, we provide a keymap "<space>sh" to [s]earch the [h]elp documentation,
    which is very useful when you're not exactly sure of what you're looking for.
