 # docker-celery-exporter
-Docker image for celery-exporter, a Prometheus exporter for Celery metrics
+
+Docker image for [`danihodovic/celery-exporter`](https://github.com/danihodovic/celery-exporter), a Prometheus exporter for Celery metrics.
+
+## Motivations
+
+### How does this differ from upstream?
+
+The current Docker image doesn't support ARM and we needed one that does. And [the review to add support](https://github.com/danihodovic/celery-exporter/pull/329) took longer than we could wait.
+
+## Usage
+
+```
+docker run --name celery-exporter zappi/celery-exporter:latest
+```
+
+For more detailed usage documentation [see upstream](https://github.com/danihodovic/celery-exporter).
