The primary source of information is the web site for the mining pool itself. Information like URL and how to specify Worker name is of most importance. Some mining algorithms also uses the concept of Wallets, that may have to be specified if required by the pool.
Pools can be added via the New pool button in the toolbar of Awesome Miner. To edit or remove a pool, use the Options dialog, Pools section.
See Mining pool configuration for information how to configure pools.
See Worker name configuration for more advanced scenarios.
