-This is nothing but a simple and barebones application (which I've quickly written in WinForms because I don't know any other application framework which allows me to get a project up and going like this) which lets me make graphics for games and applications running in VGA 256-color mode (aka `INT 10h`).
+This is nothing but a simple and barebones application (which I've quickly written in WinForms because I don't know any other application framework which allows me to get a project up and going like this) which lets me make graphics for games and applications running in the famous MCGA/VGA 256-color mode (aka Mode 13h).
 
 It uses it's own format, which you read about in the `SaveImage_Click` function in [MainForm.cs](VGAPainter/MainForm.cs). It has a header (`TGRV`), followed by two 16-bit integers (`ushort`) for width and height, finally the raw binary data.
 
 You can use it for drawing true to platform limits artwork and export it into a PNG (but why would you do that when you have Photoshop, Paint.net and GIMP?)
 
 It's not as feature complete as I'd like, but below is a wishlist of quality features I'd like to add.
 
+## Features
+
+* Import and export to and from PNG, JPEG and other common image formats;
+* A simple to understand file format for loading images onto older systems;
+* Limited, but customisable 256-color palette;
+
 ## Wishlist
 
-* Using alternate 256-color palettes (could come up with an alternate `TGRP` format for storing palettes)
-* More tools (flood fill isn't implemented, I also want rectangles and lines)
+* Refactoring (de-spaghetti-ing the code)
+* More tools (flood fill is in, but rectangles and lines are not)
