+### Usage
+
+If you want to load an asset into your `three.js` app, you have to put all external resources like `.blp` or `.skin` files into the same directory like the M2 file. Depending on the M2 version, you have to name resources files with their `FileDataID` or with their actual file name. 
+
 This loader requires `three.js` in version `r144` or higher.
