+This is a Vim extension that emulates iA Writer environment when editing Markdown, reStructuredText or text files.
+
+It requires [goyo.vim](https://github.com/junegunn/goyo.vim) and it works by setting global Goyo callbacks that triggers special setup for Markdown, reStructuredText and text files.
+
+Please note that this might not work perfectly with your colorscheme. Patches are welcome to fix this :-)
+
+## Installation and usage
+
+* Install [goyo.vim](https://github.com/junegunn/goyo.vim)
+* In command mode type :Goyo
+
+Additionally you may want to have a shortcut. Add this to your vimrc:
+
+    nnoremap <silent> <leader>z :Goyo<cr>
