 Ethermint
 ---------
 
-Build the container: Copy the ``ethermint`` binary and the setup folder
-to the ``ethermint`` folder.
+The application configuration will be stored at ``/ethermint``.
 
-::
+Initialize ethermint:
 
-    docker build -t ethermint ethermint
+::
 
-The application configuration will be stored at ``/ethermint``. The
-files required for initializing ethermint (the files in the source
-``setup`` folder) are under ``/setup``.
+    mkdir /ethermintdata
+    wget -O /ethermintdata/genesis.json https://github.com/tendermint/ethermint/raw/master/setup/genesis.json
+    docker run --rm -v /ethermintdata:/ethermint tendermint/ethermint ethermint --datadir /ethermint init /ethermint/genesis.json
 
-Initialize ethermint configuration:
+Start ethermint as a validator node: This is a two-step process: \* Run the
+tendermint container and expose the ports that allow clients to connect. \* Run
+the ethermint container. You will have to define where tendermint runs as the
+ethermint binary connects to it explicitly. The --proxy\_app should contain the
+ethermint application's IP address and port.
