+
+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! :)
