+## Stratum Server Instructions
+In simple terms, the stratum protocol is a protocol to distribute crypto mining work to multiple miners. Mining pools typically run a stratum endpoint that the various miners communicate with.
+Please refer to other web sources for more information about mining pools or the stratum protocol.
+
+When mining LBC, you can solo mine directly to an instance of a full node (using the node's wallet). Or you can mine as part of a pool. 
+You can host your own pool or use one of the many hosted LBC pools. See https://miningpoolstats.stream/lbry
+
+This document refers to Yiimp, a derivative of Yaamp, as found here: https://github.com/tpruvot/yiimp.git .
+Please refer to the instructions there as well. Yiimp has supported LBRY mining for several years.
+
+Yiimp consists of two pieces: the web GUI for pool management (written in PHP) and the Stratum server (written in C++). The two communicate via polling a MySQL database (or MariaDB).
+The web GUI and configuration of the pooling rewards, fees, etc. are out of scope here.
+
+To help you with running Yiimp, we have created two docker images: one for the DB and one for the Yiimp Stratum Server. (See the subfolders.)
+Use of the Docker images is optional; you can refer to other Yiimp and MySQL documentation for running it without Docker.
+If you are using your own database instance, you will need to import the Yiimp SQL files to establish the yaamp database.
+See https://github.com/tpruvot/yiimp/tree/next/sql .
+
+### Sample Usage Steps:
+
+#### 1. Run the full lbrycrd node:
+```
+./lbrycrdd -testnet -rpcuser=ruser -rpcpassword=rpswd -deprecatedrpc=validateaddress -deprecatedrpc=accounts -daemon
+```
+The included deprecated RPCs are required for compatibility with Yiimp.
+It will need to be caught up to the current block before it is ready.
+Remove `-testnet` for the real deal.
+#### 2. Run and initialize the datatabase:
+```
+docker run -d -e MYSQL_ROOT_PASSWORD=patofpaq -e MYSQL_DATABASE=yaamp --network host --name db lbry/yiimp_db
+
+docker exec -it db mysql -uroot -ppatofpaq
+use yaamp;
+delete from coins;
+insert into coins(name, symbol, symbol2, algo, enable, auto_ready, rpcuser, rpcpasswd, rpchost, rpcport, rpccurl, rpcencoding, hasgetinfo, hassubmitblock, usememorypool, usesegwit, auxpow) 
+  values('Local LBRY Instance', 'LBC', 'LBC', 'lbry', 1, 1, 'ruser', 'rpswd', '127.0.0.1', 19245, 1, 'utf-8', 0, 1, 0, 0, 0);
+exit
+```
+Use port 19245 for testnet, port 9245 for main.
+#### 3. Run the stratum server:
+```
+docker run --network host -d lbry/yiimp_stratum
+```
+Alternatively, to get more output or see how its called directly:
+```
+docker run --network host -it lbry/yiimp_stratum bash
+cat config/lbry.conf
+./stratum config/lbry
+```
+
+#### 4. Connect sgminer to it:
+```
+sgminer -k lbry -o stratum+tcp://127.0.0.1:3334/ -D -T -O mn824Su1wX7ip8WcNYzXwwWqvBvkeWGRo6:x
+```
+The username there is the account to receive payments from the pool. The password is unused. Tested with https://github.com/lbryio/sgminer-gm.
+You can use whatever miner you prefer.
