+
 1. pull and switch to directory `shader-toy`
 2. run `npm install`
 3. Open shader-toy folder in vscode and 'run extension'. It likely will fail

 5. try to run again. Open the shader `demos/fly_controls.glsl`
 6. with the shader window in focus, get the command window and select `ShaderToy Mod: Show GLSL Preview`
