-# Wozard Art Asset Generator
+# Wozard Art Asset Generator :art:
 > Development tool to create art assets for the game Wozard
 
+# How it works
+
+This tool uses imagmagick to create composite images from prefabricated assets. It iterates through the card colors and deck size, numbering and coloring cards. At the end it turns the 6 input images to 55 card images, enough for the full wozard deck. It preforms some post-processing to cut the edges to make them look like cards. (TODO: texture and gloss cards)
+
+# Concept
+
+By creating art work, as what is essentially cut-outs, we can programmatically combine them and modify them on the fly. This allows for quick iteration through numbered cards and guarantees consistency between all cards. We can also create cards out of assets as they come in so we can get a deck with WIP assets and replace them later with little hassle.
