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?

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