+# Inochi2D Viewer
+
+A small tool to view Inochi2D puppets.
+Go to the Releases section to download a precompiled version
+
+## Usage
+run `inochi2d-viewer.exe (puppet)` from the command prompt or drag a model on to the EXE file.  
+__Model resources need to be nearby the model for the dev version of the spec but this should change soon!__
+
+You can set the `TRANSPARENT` environment variable to `1` to have a transparent window!
+
+Scroll to Zoom, Hold rightclick to move viewport.
