I'm hitting the same problem a lot with a bunch of things.
Concourse CI is the one I'm running up against this today - I'm taking over a partially built installation which has all sorts of hard-coded config environment variables that I'm trying to figure out their purpose.
Their documentation has basic getting-started stuff[1], but doesn't list all the config variables and their use. It's open source, so I cloned the repo, but they don't directly reference the environment variables there, either.
Compare that to, say, Ansible's documentation - it exhaustively lists all the options[2] and what they're used for, with links to other related documentation.
