 This is the finished source code for the tutorial [Deploying Django with Docker Compose](https://londonappdeveloper.com/deploying-django-with-docker-compose/).
 
 In this tutorial, we teach you how to prepare and deploying a Django project to an AWS EC2 instance using Docker Compose.
+
+For Software Samurais:
+to use run this BackendApp you need to do the following step:
+1. Start the docker desktop app on your device
+2. run the command "docker-compose up"
+3. After making substantial changes you would need to rebuild the image. Preferrably by deleting the old image from the docker desktop app and running the command again.
+4. the backed app is reachable at "localhost:8000"
