-What is Kickstart?
-
-  Kickstart.nvim is *not* a distribution.
-
-  Kickstart.nvim is a starting point for your own configuration.
-    The goal is that you can read every line of code, top-to-bottom, understand
-    what your configuration is doing, and modify it to suit your needs.
-
-    Once you've done that, you can start exploring, configuring and tinkering to
-    make Neovim your own! That might mean leaving Kickstart just the way it is for a while
-    or immediately breaking it into modular pieces. It's up to you!
-
-    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
-
-Kickstart Guide:
-
-  TODO: The very first thing you should do is to run the command `:Tutor` in Neovim.
-
-    If you don't know what this means, type the following:
-      - <escape key>
-      - :
-      - Tutor
-      - <enter key>
-
-    (If you already know the Neovim basics, you can skip this step.)
-
-  Once you've completed that, you can continue working through **AND READING** the rest
-  of the kickstart init.lua.
-
-  Next, run AND READ `:help`.
-    This will open up a help window with some basic information
-    about reading, navigating and searching the builtin help documentation.
-
-    This should be the first place you go to look when you're stuck or confused
-    with something. It's one of my favorite Neovim features.
-
-    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.
-
-  I have left several `:help X` comments throughout the init.lua
-    These are hints about where to find more information about the relevant settings,
-    plugins or Neovim features used in Kickstart.
-
-   NOTE: Look for lines like this
-
-    Throughout the file. These are for you, the reader, to help you understand what is happening.
-    Feel free to delete them once you know what you're doing, but they should serve as a guide
-    for when you are first encountering a few different constructs in your Neovim config.
-
-If you experience any errors while trying to install kickstart, run `:checkhealth` for more info.
-
-I hope you enjoy your Neovim journey,
-- TJ
-
-P.S. You can delete this when you're done too. It's your config now! :)
