+## Working with Docker
+
+Prerequisites
+-------------
+
+You should have installed Docker and Docker Compose in your machine.
+
+Also if you are going to work with docker first replace the database.yml with the preconfigured file made it to work it 
+
+
+    cp config/database-docker.yml.example config/database.yml
+
+
+The First step is to build the container
+
+    sudo docker build -t consul .
+  Then run 
+  
+
+    sudo docker-compose up -d database
+   to create your application and database images.
+
+Once built you can initialize your development DB and populate it with
+
+    sudo docker-compose run app rake db:create
+    sudo docker-compose run app rake db:migrate
+    sudo docker-compose run app rake db:seed
+    sudo docker-compose run app rake db:dev_seed
+
+If you want to run the rails console just run in another terminal:
+
+
+  `sudo docker-compose run app rails console`
+    
+
+Now we can finally run the application with
+
+
+    sudo docker-compose up 
+
+To verify the containers are up execute **sudo docker ps .** You should see output similar to this:
+
+![enter image description here](https://i.imgur.com/ASvzXrd.png)
+
+now you can enter to localhost:3000 
+
+to verify that CONSUL is running
