Explain what to do if example commands fail about docs.appimage.org

[TheAssassin]

WSL is not officially supported, since it's a weird and proprietary system that requires an installation of a proprietary OS. Therefore, there is a best-effort policy for supporting WSL (as in, if someone tests some aspects and reports back, we take that into account in docs, etc.).

That said, it doesn't mean WSL can't run any AppImages. As you say, extracting them and running the contents works, especially for simpler apps (I guess something like neovim should run without any problems). It only can't run FUSE, but there's projects to work around that.

Regarding compatibility, our docs clearly state that FUSE is one of the very few runtime dependencies. It's widely spread in real Linux distributions. It's not like it isn't documented. I don't know why Microsoft market their WSL thingy as "Linux on Windows", it's pretty incomplete in terms of supporting widely used technologies.

Thanks for your feedback. I think someone should extend that section in the docs, or maybe even create a page dedicated to WSL. However, especially the latter will only happen if some WSL user takes the time to write that and send it to us as a PR.

Would you like to send a PR improving docs so they're more useful to WSL users like you? You have a much better view at things than any of us has there, I bet.
