It first of all needs to be a completely independent nation, entirely free from governance or dominion by another one, and to be able to prove that it can function as an autonomous entity economically and socially. All it need do then is simply apply to the UN for official recognition and membership, although it helps if it has the support of one or more of the world's regional power blocs first (such as the EU or The Arab League, etc.)
Whether it is granted membership then depends upon whether such a move would be opposed by other nations to such an extent that it might create regional or global instability.

A nation must apply via the Security Council. Their assessment and recommendation is passed to the General Assembly, who vote on whether or not the nation should join.
