+# Docker container description for Tendermint applications
+
+* Overview (#Overview)
+* Tendermint (#Tendermint)
+* Basecoin (#Basecoin)
+* Ethermint (#Ethermint)
+
+## Overview
+
+This folder contains Docker container descriptions. Using this folder you can build your own Docker images with the tendermint application.
+
+It is assumed that you set up docker already.
+
+If you don't want to build the images yourself, you should be able to download them from Docker Hub.
+
+## Tendermint
+
+Build the container:
+Copy the `tendermint` binary to the `tendermint` folder.
+```
+docker build -t tendermint tendermint
+```
+
+The application configuration will be stored at `/tendermint` in the container. The ports 46656 and 46657 will be open for ABCI applications to connect.
+
+Initialize tendermint configuration and keep it after the container is finished in a docker volume called `data`:
+```
+docker run --rm -v data:/tendermint tendermint init
+```
+If you want the docker volume to be a physical directory on your filesystem, you have to give an absolute path to docker and make sure the permissions allow the application to write it.
+
+Get the public key of tendermint:
+```
+docker run --rm -v data:/tendermint tendermint show_validator
+```
+
+Run the docker tendermint application with:
+```
+docker run --rm -d -v data:/tendermint tendermint node
+```
+
+## Basecoin
+
+Build the container:
+Copy the `basecoin` binary to the `basecoin` folder.
+```
+docker build -t basecoin basecoin
+```
+The application configuration will be stored at `/basecoin`.
+
+Initialize basecoin configuration and keep it after the container is finished:
+```
+docker run --rm -v basecoindata:/basecoin basecoin init deadbeef
+```
+Use your own basecoin account instead of `deadbeef` in the `init` command.
+
+Get the public key of basecoin:
+We use a trick here: since the basecoin and the tendermint configuration folders are similar, the `tendermint` command can extract the public key for us if we feed the basecoin configuration folder to tendermint.
+```
+docker run --rm -v basecoindata:/tendermint tendermint show_validator
+```
+
+Run the docker tendermint application with:
+This is a two-step process:
+* Run the basecoin container.
+* Run the tendermint container and expose the ports that allow clients to connect. The --proxy_app should contain the basecoin application's IP address and port.
+```
+docker run --rm -d -v basecoindata:/basecoin basecoin start --without-tendermint
+docker run --rm -d -v data:/tendermint -p 46656-46657:46656-46657 tendermint node --proxy_app tcp://172.17.0.2:46658
+```
+
+## Ethermint
+
+Build the container:
+Copy the `ethermint` binary and the setup folder to the `ethermint` folder.
+```
+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`.
+
+Initialize ethermint configuration:
+```
+docker run --rm -v ethermintdata:/ethermint ethermint init /setup/genesis.json
+```
+
+Start ethermint as a validator node:
+This is a two-step process:
+* Run the ethermint container. You will have to define where tendermint runs as the ethermint binary connects to it explicitly.
+* Run the tendermint container and expose the ports that allow clients to connect. The --proxy_app should contain the ethermint application's IP address and port.
+```
+docker run --rm -d -v ethermintdata:/ethermint ethermint --tendermint_addr tcp://172.17.0.3:46657
+docker run --rm -d -v data:/tendermint -p 46656-46657:46656-46657 tendermint node --proxy_app tcp://172.17.0.2:46658
+```
