Lack of Documentation: Installation

[LelouchFR]

I've been using figma-linux for a lot of time now, but I've recently changed my os to another drive. So I finished up by installing everything again, but which I find pretty strange is that, before (same os, just different drive), I had only one binary (figma-linux) in my /usr/bin directory and was working all fine. Today, I came here and took the 0.11.4 amd64 zip version, unzip it, put the figma-linux file into the /usr/bin directory, but doesn't seem to work as it was before. I've been fiddling with other version of the release, but doesn't seem to get the result that I had before. I would like to know if it could be possible to give out real steps, as the ones from the default branch (dev) is a little messy when you get to, try to install from source, or from the release too (the zipped or tarball could come with a README too), I would like to know if it is possible right here, to get a "Installation guide" with a lot of precise steps to finish with (if possible) the binary in the /usr/bin directory, so I just can simply use dmenu to just launch it.
