+# Basis Universal GPU Texture Compression
+
+Basis Universal is a "[supercompressed](http://gamma.cs.unc.edu/GST/gst.pdf)"
+GPU texture and texture video compression system that outputs a highly
+compressed intermediate file format (.basis) that can be quickly transcoded to
+a wide variety of GPU texture compression formats.
+
+[GitHub](https://github.com/BinomialLLC/basis_universal)
+
+## Transcoders
+
+Basis Universal texture data may be used in two different file formats:
+`.basis` and `.ktx2`, where `ktx2` is a standardized wrapper around basis texture data.
+
+For further documentation about the Basis compressor and transcoder, refer to
+the [Basis GitHub repository](https://github.com/BinomialLLC/basis_universal).
+
+The folder contains two files required for transcoding `.basis` or `.ktx2` textures:
+
+* `basis_transcoder.js` — JavaScript wrapper for the WebAssembly transcoder.
+* `basis_transcoder.wasm` — WebAssembly transcoder.
+
+Both are dependencies of `THREE.KTX2Loader` and `THREE.BasisTextureLoader`:
+
+```js
+var ktx2Loader = new THREE.KTX2Loader();
+ktx2Loader.setTranscoderPath( 'examples/js/libs/basis/' );
+ktx2Loader.detectSupport( renderer );
+ktx2Loader.load( 'diffuse.ktx2', function ( texture ) {
+
+	var material = new THREE.MeshStandardMaterial( { map: texture } );
+
+}, function () {
+
+	console.log( 'onProgress' );
+
+}, function ( e ) {
+
+	console.error( e );
+
+} );
+```
