 #### DOCKER IMAGE CONSTRUCTION
 
 You need to log in to DockerHub before you execute the create_image.sh script. This script creates the new image and pushes it to DockerHub.
 
 Create an account in DockerHub and execute in your command console:
-` $ docker login `
 
-Execute .create_image.sh ` <username>/<name_of_the_new_image> `
+``` $ docker login ```
+
+Execute 
+
+``` $ ./create_image.sh  <name_of_the_new_image> ```
+
+Note that you must edit the script in order to **add your DockerHub user**. If not, you won't be able to upload the image.

+``` $ heroku container:login ```
 
 Execute these commands
-` $ heroku create <application_name> `
+
+``` $ heroku create <application_name> ```

+
+``` $ heroku addons:create heroku-postgresql --app <application_name> ```
+
 (Adds the postgresql database to the application)
-` $ heroku config:set SERVER_SSL_ENABLED=false --app <application_name> `
-` $ heroku config:set SPRING_JPA_HIBERNATE_DDL-AUTO=update --app <application_name> `
+
+``` $ heroku config:set SERVER_SSL_ENABLED=false --app <application_name> ```
+
+``` $ heroku config:set SPRING_JPA_HIBERNATE_DDL-AUTO=update --app <application_name> ```
+
 (These commands stablish some environment variables)
+
 If you haven't uploaded the app image  to DockerHub is time to do it ;).
-` $ docker pull <dockerHub_image_name> `
+
+``` $ docker pull <dockerHub_image_name> ```
+
 (Downloads the image from DockerHub)
-` $ docker tag <dockerHub_image_name> registry.heroku.com/<application_name>/web `
+
+``` $ docker tag <dockerHub_image_name> registry.heroku.com/<application_name>/web ```
+
 (Prepares it to be pushed to Heroku)
-` $ docker push registry.heroku.com/<application_name>/web `
+
+``` $ docker push registry.heroku.com/<application_name>/web ```
