And the beautiful part is that the Info.lua file is actually used to register the commands, so when a command or subcommand is added in the code, it automatically gets documented, at least the fact that it exists.
Of course, there's still the issue of writing the real documentation, all the "sauce" around setup, each individual command etc., but in the end even that pays off because it allows us, as developers, verify that our code does what we want it to do. Especially when the command has several variations of parameters that it accepts, such as the "/gallery name" command.
Now we need to document the Info.lua file format and make other plugins' authors actually use it
That's gonna be the hardest part.
