+# Integrate OnCall
+
+> This is a working copy from [Doc](https://github.com/grafana/oncall/blob/dev/README.md).
+
+## Getting Started
+
+We prepared multiple environments:
+
+- [production](https://grafana.com/docs/grafana-cloud/oncall/open-source/#production-environment)
+- [developer](./dev/README.md)
+- hobby (described in the following steps)
+
+1. Download [`docker-compose.yml`](docker-compose.yml):
+
+   ```bash
+   curl -fsSL https://raw.githubusercontent.com/grafana/oncall/dev/docker-compose.yml -o docker-compose.yml
+   ```
+
+2. Set variables:
+
+   ```bash
+   echo "DOMAIN=http://localhost:8080
+   COMPOSE_PROFILES=with_grafana  # Remove this line if you want to use existing grafana
+   SECRET_KEY=my_random_secret_must_be_more_than_32_characters_long" > .env
+   ```
+
+   an .env with `
+
+    ```
+    DOMAIN=http://localhost:8080  # verify the port is correct
+    SECRET_KEY=my_random_secret_must_be_more_than_32_characters_long  # just for demonstration
+    ```
+
+3. Launch services:
+
+   ```bash
+   docker-compose pull && docker-compose up -d
+   ```
+
+4. Go to [OnCall Plugin Configuration](http://localhost:3000/plugins/grafana-oncall-app), using log in credentials
+   as defined above: `admin`/`admin` (or find OnCall plugin in configuration->plugins) and connect OnCall _plugin_
+   with OnCall _backend_:
+
+   ```text
+   OnCall backend URL: http://engine:8080
+   ```
+
+5. Enjoy! Check our [OSS docs](https://grafana.com/docs/grafana-cloud/oncall/open-source/) if you want to set up
+   Slack, Telegram, Twilio or SMS/calls through Grafana Cloud.
+
+## Update version
+
+To update your Grafana OnCall hobby environment:
+
+```shell
+# Update Docker image
+docker-compose pull engine
+
+# Re-deploy
+docker-compose up -d
+```
+
+After updating the engine, you'll also need to click the "Update" button on the [plugin version page](http://localhost:3000/plugins/grafana-oncall-app?page=version-history).
+See [Grafana docs](https://grafana.com/docs/grafana/latest/administration/plugin-management/#update-a-plugin) for more
+info on updating Grafana plugins.
