+### SMTP Configuration
+
+To configure Moodle to send email using SMTP you can set the following environment variables:
+ - `SMTP_HOST`: SMTP host.
+ - `SMTP_PORT`: SMTP port.
+ - `SMTP_USER`: SMTP account user.
+ - `SMTP_PASSWORD`: SMTP account password.
+ - `SMTP_PROTOCOL`: SMTP protocol.
+
+This would be an example of SMTP configuration using a GMail account:
+
+ * docker-compose:
+
+```
+  application:
+    image: bitnami/moodle:latest
+    ports:
+      - 80:80
+    environment:
+      - SMTP_HOST=smtp.gmail.com

+      - SMTP_USER=your_email@gmail.com
+      - SMTP_PASSWORD=your_password
+    volumes_from:
+      - application_data
+```
+
+* For manual execution:
+
+```
+ $ docker run -d -e SMTP_HOST=smtp.gmail.com -e SMTP_PORT=587 -e SMTP_USER=your_email@gmail.com -e SMTP_PASSWORD=your_password -p 80:80 --name moodle -v /your/local/path/bitnami/moodle:/bitnami/moodle --net=moodle_network bitnami/moodle
