Thanks for your thoughtful reply, especially the difference between the zip file and the AppImage. At the moment, I do not think the instructions are sufficient for me to build this myself. There are far too many parts that are not sufficiently explained, and involve knowing about a lot of things whose links simply dump one to a page, but do not tell one how to do anything. "In the old days", gee I hate putting it that way, one would follow a recipe. 1) install the dependencies and 2) make the build. It's not clear what exactly the dependencies are, nor where they are to be found, or how to get them on one's system. At least that's my perspective. Hope the docs improve, as I'd really like to try this, but I don't even know what yarn is, or why it is needed. Thanks for any and all help.
