+## How to Tweak
+
+To change RPGUI into your own theme the easiest thing to do is to replace the images in dist/img/ folder.
+The name of the files should be pretty easy to understand and change.
+
+To change the css rules / JavaScript itself you will need to edit the source files. RPGUI wasn't originally planned to be a distributed lib (it was taken out of a hobby project) and as such its not written in the most flexible / generic way.
+
+Feel free to create alternatives of RPGUI and publish them as different themes.
