Install from source needs to be dockumented (sic).

[rwmacleod]

Description

The Linux install instructions suggest downloading a pre-compile binary. That's not a typical workflow for open source.
I was able to build using the Docker env required by the Makefile but I don't see an executable.
Can you document how to get the executable out of docker and onto the user's desktop?

Steps to reproduce

$ make

Is this just obvious to people who are familiar with using docker to build rather than building on the host ?
