How do I define a function to execute as a command with M-x?

Question

I wish to M-x my-func and let my code run. This seems basic but where can I get more documentation about this, if possible inside emacs itself?

You need to distinguish between a common function and an interactive command. The latter is also a function, but with the addition of (interactive) to its body.

You can run the latter, but not the former, by binding commands to keys or calling them by name via M-x. See the elisp manual links above more more details.

A simple example:

(defun hello-world ()
  "Insert \"Hello World!\"."
  (interactive)
  (insert "Hello World!\n"))
