-Spritify
+### About
 
-When an animation render is complete, all of the frames in the animation are
-compiled into a single spritesheet usable for sprite-based games.
+This [Blender](https://blender.org) add-on will compile all rendered frames from your animation into a very nice and configurable sprite sheet, that's usable for sprite-based video games and even in modern cool websites.
+It can also generate animated gifs, allowing you to easily showcase and preview animations without needing to use any code at all, which usually comes in very handy.
 
-There is a Spritify panel in Render Properties where you configure some of the
-attributes of the sprite sheet as well as enable/disable the ability to
-automatically generate a sprite sheet each time an animation render completes.
+It was originally developed for use in the amazing [Ancient Beast](https://AncientBeast.com) eSport game project but sharing is caring! 🌟
+
+### Requirements
+
+This add-on requires that you have [ImageMagick](https://imagemagick.org) installed on your computer and the montage command is in your system path.
+It also assumes that you're rendering a sequence of still frames. Video renders will not work, so keep that in mind.
 
-As of version 0.4.0, Spritify will also optionally generate an animated GIF.
+### Installation
 
-Originally developed for use in the Ancient Beast (http://www.ancientbeast.com/)
