 Retro groove color scheme for Vim.
 
-Well, it's just pretty first draft. Scheme is under active development right now, so you should check it maybe a month later.
+Gruvbox is heavily inspired by [badwolf][], [jellybeans][] and [solarized][].
 
-Gruvbox is designed as a bright theme with pastel 'retro groove' colors and light/dark mode switching in the way of [Solarized][]. The main focus when developing Gruvbox is to keep colors easily distinguishable, contrast enough and pleasant for the eyes.

-That's a draft shot though it'll give you an approximate view of scheme.
+Colorscheme is in early development stage, so this could serve as working preview.
