+To spawn a new instance of Moodle it's necessary to create a folder with the Moodle source and create both container needed. The following script download Moodle from main GIT repository and create both containers (PHP and Postgres).
 
 ```
 ./start-containers.sh
 ```
 
 The start-containers.sh script:
-  - If it's first time, it will create both docker containers needed (PHP server and DB).
+  - If it's first time, it will download last Moodle version from GIT and create both docker containers needed (PHP server and DB).
   - If the containers are created, it will start them.
 
 In both cases, at the end of the execution are showed the instructions to access them. By default:
 
 ```
-To connect to PostgreSQL: host:port=127.0.0.1:32769, dbuser=moodle, dbpwd=secret
 To access Moodle: http://127.0.0.1:8000
-To enter shell in moodle container shell: docker exec -it moodle_core-php bash

+
+By default, the script creates a docker with Moodle 3.3. It's possible create a Moodle 3.2 docker with the following callback:
+
+```
+./start-containers.sh moodle32

 ## Caveats
-The following aren't handled, considered, or need work:
+The following aren't included:
 * moodle cronjob (should be called from cron container)
-* log handling (stdout?)
+* log handling. Logs are stored in the default stout (/var/log/apache2/).
 * email (does it even send?)
