 ##  With Docker and Docker compose
 
-To install it, run the following commands (Docker must be installed on your system):
+### Install the project prerequisites
+The project has prerequisites:
+
+- [Docker][docker] (1.12+)
+- [Docker-composer][docker-compose] (1.10+)
+- [GNU make][make]
+
+To install Docker, refer to the official documentation for your operating system: https://docs.docker.com/engine/installation/.
+
+Once Docker installed, to check its smooth running, run docker -v, you should get something like suit:
+
+```
+$ docker -v
+Docker version 1.12.4, build 1564f02
+```
+> You must use the minimum version 1.12 of Docker.
+
+To install the docker-composer, please also refer to the official documentation: https://docs.docker.com/compose/install/.
+
+Once docker-composes installed (install it globally to be able and access from anywhere), to check its proper functioning, run docker-compose -v, you should get something like suit:
 
 ```
-$ docker-compose up -d # Download, build and run Docker images
-$ sh docker-ssh # ssh into local docker instance"
-$ php certificationy.php # Run Certificationy CLI
-$ exit # To exit bash docker
+$ docker-compose -v
+Docker-composer version 1.10.0, build 4bd6f1a
+```
+
+> You must use the docker-compose version 1.10 minimum.
+
+A makefile allows you to manipulate the container simply and easily.
+You have to be able to run `make -v`, which you are ready to choose:
+
+```
+$ make -v

+> Command to be able to use `make` which will greatly facilitate the work.
+
+### Using the Container
+
+You should then be able to run `make` which will show you using the Makefile:
+
+```
+$ make
+start:           Start the project
+bash:            Go to the bash container of the application
+stop:            Stop docker containers
+```
+
+Start the application with `make start`:
+
+```
+$make start
+docker-compose build
+Building app
+Step 1/19 : FROM php:7.1-fpm-alpine
+7.1-fpm-alpine: Pulling from library/php
+... # pulling image
+Successfully built 22ab66e58936
+Successfully tagged certificationycli_app:latest
+docker-compose up -d
+Recreating certificationycli_app_1
+docker exec -i -t 6929cb80f7a7df579910341c74208e05d6d5548900488c35b41c281da9fe940e /bin/bash
+bash-4.3# 
+```
+
+Once the procedure is complete you can already use the bash of the container.
+Run Certificationy CLI;
+
+```
+$ php certificationy.php
+```
+
+To exit bash docker
+
+```
+$ exit 
+```
+
+Stop the application with `make stop`:
+
+```
+$ make stop 
+docker-compose kill
+Killing certificationycli_app_1 ... done
 ```
