+# This is the help for the nixCats lazy wrapper
+
+Or well, most of the help for it. There is also help for it at [:h nixCats.luaUtils](https://nixcats.org/nixCats_luaUtils.html)
+
+It is the entirety of [kickstart.nvim](https://github.com/nvim-lua/kickstart.nvim) with very few changes, but uses nixCats to download everything
+
+enter a new directory then run:
+
+`nix flake init -t github:BirdeeHub/nixCats-nvim#kickstart-nvim`
+
+then to build, `nix build .`
+
+and the result will be found at `./result/bin/nvim`
+
+It also can work without any nix whatsoever.
+It has been adapted such that it works either way!
+
+All notes about the lazy wrapper are in comments that begin with the string: `NOTE: nixCats:` so to find all of the info, search for that.
+
+One other note.
+
+If you install your grammars via `lazy.nvim` rather than `nix`, you will need to add a c compiler to your `lspsAndRuntimeDeps` section in your `categoryDefinitions`
+
+If you install your grammars via nix, the only methods supported via the `lazy.nvim` wrapper are the following.
+
+Summary: as long as `pkgs.neovimUtils.grammarToPlugin` is called on it somehow, it will work.
+
+Any other ways will still work in nixCats, but not when using the lazy wrapper, because the lazy wrapper has to add them back to the runtimepath.
