Men are only necessary to maintain balance. Oopss.. wait, before you react..please..that’s not what I’m going to write about here. 
The man page is the three letter command for Manual Pager Utils. It’s the command-line counterpart of Help files and documentation – that helps users figure out how to use a specific feature.
to use it, open a Terminal Window and type
man appname
Where appname is the command that you want to see how to use. For example, if you want to see the man page for man, type man man (yep, that works, see pic).
You can use the scroll wheel of your mouse to scroll up and down, or you could use the arrow keys up and down. If you want to close the man page, simply press q (the letter q on your keyboard) and it’ll take you back to the terminal (well, technically, you’re still there).
