-This folder contains two files:
+Basis Universal texture data may be used in two different file formats:
+`.basis` and `.ktx2`. Texture data is identical in both cases, but different
+transcoders are required to read the two file types. Both transcoders are
+available in this folder now, but they may be merged in the future.

+### .ktx2
+
+The folder contains two files required for transcoding `.ktx2` textures:
+
+* `msc_basis_transcoder.js` — JavaScript wrapper for the WebAssembly transcoder.
+* `msc_basis_transcoder.wasm` — WebAssembly transcoder.
+
+Currently, the `msc_basis_transcoder.js` file must be added to the page as a
+global script. The WASM transcoder will be downloaded from the same directory
+automatically. These will likely be replaced with ES modules, and merged with
+the `.basis` transcoder, in the future. See `KTX2Loader` for usage.
