 Mr T
 ====
 
-Textmate-like file finder on a curses interface. Intended for file completion on
-shell prompt. 
+What is it.
+-----------
 
-Mr T requires a ruby compiled with curses devel, it also makes use of the ruby 
-extension provided by (Command-T)[https://wincent.com/products/command-t]
+Mr T is a curses based file finder. If you're familiar with Textmate's cmd-t or
+Vim's Command-T plugin, you'll feel right at home. 
 
+Mr T allows you to have fast, file completion from your shell prompt. You can 
+use it as-is by invoking the _mrT_ command, or use it as your default file
+completion strategy for some unix commands.
 
-== Basic Usage
 
-     mrT [basedir]
+Requirements
+------------
 
-== TODO
+Mr T requires a ruby compiled with the standard curses library (you need to have
+curses-devel installed at ruby configuration time), it also makes use of the ruby 
+extension provided by [Command-T][http://wincent.com/products/command-t]
+
+
+Installation
+------------
+
+rake install
+
+
+
+Usage
+-----
+
+After installation, you might be able to use the _mrT_ binary, right now it 
+takes an optional directory as only argument.
+
+     mrT
+
+
+Future
+------
+
+Use Command-T caching features, expose Command-T options as command line flags.
+
+
+Contribute
+----------
+
+Feel free to adapt mrT to your needs, report any issue or send pull requests 
+to the github repository:
