Provide instructions for mixing and matching

Hello. Thanks for these fonts! I have newly downloaded and installed and configured a few in various applications (one for Konsole terminal, one for Kate/KWrite, one for Jupyter) as they look nice.

However I do not find any official instructions for Mixing and Matching. As I use VS Code but am not an expert, I am not sure how to do this myself.

I find a few instructions by searching: [1](https://stackoverflow.com/questions/76049850/how-can-i-change-the-font-of-inline-suggestions-in-vs-code), [2](https://github.com/githubnext/monaspace/issues/30), [3](https://github.com/githubnext/monaspace/issues/6) etc.

There seem to be different guidelines, requirements for custom plugins (like APC, Custom CSS) etc so I am not sure what to do. It would hence be good if you could provide some official guidelines at least by creating a Wiki here on GitHub.

Thanks!
