 # Anm2ed
 
-Reimplementation of *The Binding of Isaac: Rebirth*'s proprietary animation editor; dealing with manipulating the XML-based ".anm2" format.
+![Preview](https://shweetz.net/https://shweetz.net/files/projects/anm2ed/preview.png)
+
+A reimplementation of *The Binding of Isaac: Rebirth*'s proprietary animation editor. Manipulates the XML-based ".anm2" format, used for in-game tweened animations.
+
+## Features
+
+- Most things present in the original IsaacAnimationEditor.exe, except some stuff like drawing (why not use an art program!)
+- Smooth [Dear ImGui](https://github.com/ocornut/imgui) interface; docking, dragging and dropping, etc.
+- Keybinds/keyboard control for common actions(see [src/input.h](https://github.com/ShweetsStuff/anm2ed/blob/master/src/input.h))
+
+### To do
+- Windows release
+- Undo queue
+- GIF export
+- Some other things I can't think of
+
+### Known Issues
+- Root Transform doesn't work for scale/rotation (matrix math is hard; if you can help me fix it I will give you $100.)
+- Some .anm2 files used in Rebirth might not render correctly due to the ordering of layers; just drag and drop to fix the ordering and save, they will work fine afterwards. 
+- On startup, you will have to configure the windows yourself.
+- Probably several bugs that elude me
