 Joining a mining pool
 ---------------------
 
-* **Choosing a pool**: We highly recommend joining a mining pool rather than mining solo. It provides a more steady income stream based on the hash rate contributed, rather than only getting paid when your ASIC mines a block. In choosing a mining pool, you can consider the size of the pool, payout methods (PPS vs PPLNS), pool fee, geographic location of the pool, ping time to the server, user interface, statistics / data, and customer support. Ultimately you want to find a pool that can be trusted, has high payouts and a great user experience. A list of pools can be found `here <https://www.zcashcommunity.com/mining/mining-pools/>`_.

+We recommend the following mining pools, which are asic-compatible *and* support payment out to shielded addresses: `Luxor <https://mining.luxor.tech/>`_, `Bitfly <https://zcash.flypool.org/>`_, and `Slushpool <https://slushpool.com/>`_.   
 
 * **Completing Configuration**: Once you have created a user account with a chosen mining pool, you will need to complete the setup process at the specific mining pool so that the ASIC is registered as a mining participant in the mining pool. We recommend that you contact the chosen mining pool directly with any assistance.
