+## Docker Compose
+
+The project also comes with a *docker-compose.yml* file for running the docker images. 
+
+To run the images first you need to buid them and publish them to your local docker registry. 
+
+You can do that by running:
+
+1) ``./gradlew dbt-executor:distDocker``
+2) ``./gradlew dbt-ledger:distDocker``
+
+After you have generated the Docker images you can run them both by running ``docker-compose up`` in the root folder. 
+
+The ledger will be available at http://localhost:5050/ledger and the executor 
+will be available at http://localhost:5051/executor

+## How to make a distributed transaction (in a ratpack application)
+
+Once you have the executor and the ledger configured and running, you can start making transactions to the database 
+the executor is connected to.
+
+By default the executor will set up an in-memory database without any tables, so the first transaction you want to make
+is to create the table you want.
