+# Github Latest Release Exporter
+This is a simple service that fetches the latest version of software from github and exposes it as a metric for Prometheus to scrape.
+Just query the endpoint with ```owner/repository``, and you will get a metric back.
+
+
+## Development and local testing
+```bash
+docker buildx build -t latest_release_exporter .
+docker run --name latest_release_exporter -d -p 8000:8000 -e GITHUB_TOKEN=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 latest_release_exporter
+curl http://localhost:8000/metrics?repo=prometheus/prometheus
+
+docker stop latest_release_exporter
+docker rm latest_release_exporter
+```
