-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:
-
-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! :)
