+# lbrycrd Docker image
+`
+
+## Configuration
+
+The lbrycrd container comes with a default configuration you can use for
+production. Extra configuration is optional.
+
+The container includes a `start` script that offers a flexible configuration
+style. It allows you to mount your own `lbrycrd.conf` file, or use environment
+variables, or a mix of both.
+
+### Environment variables
+
+The environment variables override the values in the mounted config file. If no
+mounted config file exists, these variables are used to create a fresh config.
+
+ * `PORT` - The main lbrycrd port
+ * `RPC_USER` - The rpc user
+ * `RPC_PASSWORD` - The rpc user's password
+ * `RPC_ALLOW_IP` - the subnet that is allowed rpc access
+ * `RPC_PORT` - The port to bind the rpc service to
+ * `RPC_BIND` - The ip address to bind the rpc service to
+ 
+
+### Example run commands
+
+Running the default configuration:
+
+```
+docker run --rm -it -e RUN_MODE=default -e SNAPSHOT_URL="https://lbry.com/snapshot/blockchain" lbry/lbrycrd:latest-release
+```
+
+Running with RPC password changed:
+
+```
+docker run --rm -it -e RUN_MODE=default -e RPC_PASSWORD=hunter2 lbry/lbrycrd:latest-release
+```
+
+Running with a config file but with the RPC password still overridden:
+
+```
+docker run --rm -it -v /path/to/lbrycrd.conf:/etc/lbry/lbrycrd.conf -e RUN_MODE=default -e RPC_PASSWORD=hunter2 lbry/lbrycrd:latest-release
+```
