 This is a docker container that runs a Prometheus exporter for [Frigate](https://frigate.video/) stats.
 
-Tested with ghcr.io/blakeblackshear/frigate:0.12.0-beta6 docker image with a single Intel OpenVINO detector.

 ## Run the exporter
 
-Modify the `FRIGATE_STATS_URL` environment variable below to point to your [Frigate API stats](https://docs.frigate.video/integrations/api#get-apistats). Then run the container:
+Modify the `FRIGATE_STATS_URL` environment variable below to point to your [Frigate API stats](https://docs.frigate.video/integrations/api#get-apistats) (replace `<your-frigate-ip>` with your Frigate docker container IP address). Then run the container:
 
 ```bash
-docker run -d -p 9100:9100 -e "FRIGATE_STATS_URL=http://<your-frigate-ip>:5000/api/stats" --name prometheus_frigate_exporter rhysbailey/prometheus-frigate-exporter
+docker run \
+    -d \
+    --restart unless-stopped \
+    -p 9100:9100 \
+    -e "FRIGATE_STATS_URL=http://<your-frigate-ip>:5000/api/stats" \
+    --name prometheus_frigate_exporter \
+    rhysbailey/prometheus-frigate-exporter
 ```
 
 Metrics are available at http://localhost:9100/metrics
+
+### Setup Prometheus
+
+If you don't already have Prometheus set up to scrape the `prometheus-frigate-exporter` metrics,
+
+- create Prometheus config file `prometheus.yml`
+- copy example below into `prometheus.yml`, replacing `<your-prometheus-frigate-exporter-ip>` with the IP address of your `prometheus_frigate_exporter` docker container. `<your-prometheus-frigate-exporter-ip>` is likely the same IP address as your Frigate docker containers `<your-frigate-ip>` if running in the same docker instance 
+  ```yaml
+  # my global config
+  global:
+    scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
+    evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
+    # scrape_timeout is set to the global default (10s).
+   
+  # A scrape configuration containing exactly one endpoint to scrape:
+  # Here it's Prometheus itself.
+  scrape_configs:
+    # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
+    - job_name: "prometheus"
+      static_configs:
+        - targets: ["localhost:9090"]
+  
+    - job_name: "prometheus_frigate_exporter"
+      static_configs:
+        - targets: [
+                      "<your-prometheus-frigate-exporter-ip>:9100"
+                   ]
+  ```
+
+- Run Prometheus docker container by replacing `/path/to/prometheus.yml` to point to the `prometheus.yml` just created
+
+  ```bash
+  docker run \
+      -d \
+      --restart unless-stopped \
+      -p 9090:9090 \
+      -v /path/to/prometheus.yml:/etc/prometheus/prometheus.yml \
+      prom/prometheus
+  ```
+
+To see if Prometheus is scraping the Frigate exporter, go to Prometheus targets page [http://<your-prometheus-ip>:9090/targets]() and look for `UP` for `prometheus_frigate_exporter` job.
+
+### Setup Grafana
+
+If you don't already have Grafana set up, 
+
+- run Grafana
+
+    ```bash
+    docker run \
+        -d \
+        --restart unless-stopped \
+        -p 3000:3000 \
+        grafana/grafana-oss
+    ```
+
+- Go to Grafana [http://<your-grafana-ip>:3000]() (might take a few minutes first run). Use admin:admin to log in
+- Go to [http://<your-grafana-ip>:3000/datasources]()
+  - add Prometheus datasource
+  - Set Prometheus URL `http://<your-prometheus-frigate-exporter-ip>:9090`
+  - Click `Save and Test` to check if connected
+- Go to [http://<your-grafana-ip>:3000/dashboards]()
+  - New -> Import
+  - Enter in `Import via grafana.com`: `18226` (can be found at [Grafana Dashboard](https://grafana.com/grafana/dashboards/18226-frigate/)) and click Load
+  - Set the datasource as Prometheus instance set up before then click Import
+- Should now be able to see Frigate time series metrics in the Grafana dashboard
+
