Description of problem:

I don't see any manpage shipped for composer-cli command.
Additionally I don't see any example for basic composer-cli commands such as "composer-cli sources add", which requires a specific undisclosed format to specify your own repository.

Same is expected from "composer-cli blueprints show <Blueprint>" and other commands as well.
This needs to be properly documented.

Additionally, executing "composer-cli sources add" without any file name doesn't report an error.

Very likely more commands behave similarly but I have no time giving an exhaustive list.

Version-Release number of selected component (if applicable):

composer-cli-28.14.55-2.el8.x86_64

How reproducible:

ALWAYS
