+## Compose sample application
+### Django application in dev mode
+
+Project structure:
+```
+.
+├── compose.yaml
+├── app
+    ├── Dockerfile
+    ├── requirements.txt
+    └── manage.py

+```
+

+services: 
+  web: 
+    build: app 
+    ports: 
+      - '8000:8000'

+
+## Deploy with docker compose
+
+```
+$ docker compose up -d

+
+## Expected result
+
+Listing containers must show one container running and the port mapping as below:
+```
+$ docker ps
+CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS              PORTS                    NAMES

+```
+
+After the application starts, navigate to `http://localhost:8000` in your web browser:
+
+Stop and remove the containers
+```
+$ docker compose down
