How do I find documentation for this Emacs command?

Question

This question shows how to change a particular Emacs setting with set-face-attribute.

Where can I find documentation on set-face-attribute?

Normally I find documentation by C-h a, followed by a command or fragment of a command. But doing this for set-face-attribute turns up nothing.

Standard way to get description of function is C-h f - press it and type function name (you can use TAB to complete function name).

If you'll press C-h ? - you'll get list of all help functions. Another useful keybinding is C-h v - to get description of variable.
