-A Lush Theme for Neovim.
-===
+# darcula_lush
+
+A dark [Lush](https://github.com/rktjmp/lush.nvim) theme for Neovim.
+
+The theme includes both its full RGB palette and a dark 16-color ANSI
+fallback. With `termguicolors` disabled, Neovim uses the `cterm` colors, so the
+theme remains usable in a Linux console or another TTY without true color or
+256-color support.
 
 See: http://git.io/lush.nvim for more information on Lush and a helper script
 to setup your repo clone.
