-Prometheus Exporter for Jitsi Meet written in Go.
+Prometheus Exporter for Jitsi Meet written in Go. Based on [Jitsi Meet Exporter](https://git.autistici.org/ai3/tools/jitsi-prometheus-exporter) from [Autistici](https://www.autistici.org/)
+
+There's multiple different [statistics endpoint that can be exposed by jitsi](https://github.com/jitsi/jitsi-videobridge/blob/master/doc/statistics.md) (like /stats and /colibri/stats); you can configure the used URL with the `videobridge-url`.
+The exporter will handle both of them, but some metrics that aren't exposed may be reported as 0.
+
+## Usage
+
+```
+go install github.com/systemli/prometheus-jitsi-meet-exporter@latest
+$GOPATH/bin/prometheus-jitsi-meet-exporter
+```
+
+### Ansible
+
+We also provide an [Ansible Role to install and configure the Jitsi Meet Exporter](https://github.com/systemli/ansible-role-jitsi-meet-exporter).
+
+Example Playbook:
+
+```yaml
+- hosts: jitsimeetservers
+  roles:
+     - { role: systemli.jitsi_meet_exporter }
+```
+
+### Docker
+
+```
+docker run -p 9888:9888 systemli/prometheus-jitsi-meet-exporter:latest -videobridge-url http://jitsi:8080/colibri/stats
+```
+
+## Dashboard
+
+See the [Grafana Dashboards](dashboards) in this repository.
+
+### Example
+
+![Jitsi Meet Dashboard](dashboards/jitsi-meet.png)
+
+## Metrics
+
+```
+# HELP jitsi_threads The number of Java threads that the video bridge is using.
+# TYPE jitsi_threads gauge
+jitsi_threads 0
+# HELP jitsi_bit_rate_download The total incoming bitrate for the video bridge in kilobits per second.
+# TYPE jitsi_bit_rate_download gauge
+jitsi_bit_rate_download 0
+# HELP jitsi_bit_rate_upload The total outgoing bitrate for the video bridge in kilobits per second.
