What can I say instead of "what to do"?

You can use alternatives like "<a href="/s/how+to+proceed" target="_blank" rel="alternative">how to proceed", "<a href="/s/what+action+to+take" target="_blank" rel="alternative">what action to take" or "<a href="/s/the+next+steps" target="_blank" rel="alternative">the next steps" depending on the context.

Which is correct, "what to do" or "what to be done"?
