 The console will display a `localhost` URL for local testing, and (on supported WiFi networks and devices) may also display an IP address accessible by other devices on the same network. Note that mobile devices must support WebAssembly to run this demo.

-## Building transcoder locally
-
-Prebuilt versions of `basis_transcoder.js` and `basis_transcoder.wasm` are included in the `transcoder/build/` folder, and are sufficient for local demos. To build the transcoder yourself, first install emscripten ([tutorial](https://webassembly.org/getting-started/developers-guide/)) and cmake ([download](https://cmake.org/download/)). Then run:
-
-```shell
-cd webgl/transcoder/build/
-emcmake cmake ../
-make
-```
