I'm fine with it, but I'm not sure should it be placed at nuttx/Documentation since all codes is in apps side, and only part of apps can be compiled to Wasm module.

BTW, I put it here first because apps/Documentation is not exist.

Yes, all documentation is in nuttx repo, also documentation for apps https://github.com/apache/nuttx/tree/master/Documentation/applications which later can be found here https://nuttx.apache.org/docs/latest/applications/index.html
