+# Django Channels & Redis & Postgres
+
+[![1-click-deploy](https://defang.io/deploy-with-defang.svg)](https://portal.defang.dev/redirect?url=https%3A%2F%2Fgithub.com%2Fnew%3Ftemplate_name%3Dsample-django-channels-redis-template%26template_owner%3DDefangSamples)
+
+This sample demonstrates how to get Django Channels up and running with Redis and Postgres both managed by Defang. It demonstrates how to do this with a simple chat application.
+
+## Prerequisites
+
+1. Download [Defang CLI](https://github.com/DefangLabs/defang)
+2. (Optional) If you are using [Defang BYOC](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html) authenticated with your AWS account
+3. (Optional for local development) [Docker CLI](https://docs.docker.com/engine/install/)
+
+## Development
+
+To run the application locally, you can use the following command:
+
+```bash
+docker compose -f compose.dev.yaml up
+```
+
+This will start the Django server, Redis, and Postgres and mounts your Django app so you get live reloading. You can access the Django server at `http://localhost:8000`.
+
+## Configuration
+For this sample, you will need to provide the following [configuration](https://docs.defang.io/docs/concepts/configuration). Note that if you are using the 1-click deploy option, you can set these values as secrets in your GitHub repository and the action will automatically deploy them for you.
+
+### `SECRET_KEY`
+The secret key for your Django application. You can generate a new one by running `python -c 'from django.core.management.utils import get_random_secret_key; print(get_random_secret_key())'`. A default, insecure key is used if this is not set, but you should set it for a production deployment.
+
+### `POSTGRES_PASSWORD`
+The password for your Postgres database. You need to set this before deploying for the first time.
+
+## Deploying
+
+1. Open the terminal and type `defang login`
+2. Use the [`defang config`](https://docs.defang.io/docs/concepts/compose#configuration) command to setup environment variables.
+3. Type `defang compose up` in the CLI.
+4. Your app will be running within a few minutes.
