 # Org-mode syntax highlighting for Vim
 
-TODO: test with other colorthemes
-TODO: fix italics
-TODO: fix hyperlinks
+This is a minimal [Org-mode](https://orgmode.org/) plugin for Vim. It provides
+only the absolute necessities (e.g. syntax highlighting, indentation, folding,
+etc.). The goal of this plugin is to replicate Vim's existing
+[Markdown](https://github.com/tpope/vim-markdown/) editing experience for
+Org-mode files.
+
+**NOTE**: This plugin is still a work in progress.
