I highly recommend:

cmd —help

man cmd

ls -la /usr/share/doc/cmd

While some of the language can be daunting, it is generally good reads. And these days we have ChatGPT etc that can help explain tricky words etc in more context, even if you native language is not English.

My new default advice actually for junior developers here in Sweden. Works for many other tech areas too, not just the terminal.

Ah, yes. In English we used to spell that R-T-F-M.
