 # GitHub runner operators
 
-
 ![WIP](https://img.shields.io/badge/status-WIP-yellow)
 
 A monorepo containing charms to operate Self-Hosted GitHub Action Runners.
 
-At the moment, it contains initial code for the `webhook-gateway`
-application, that receives and forwards GitHub webhooks to an AMQP queue.
+## Repository layout
+
+```
+charms/
+  planner-operator/         # Juju charm: GitHub runner planner
+    cos_custom/
+      grafana_dashboards/   # Grafana dashboards for the planner charm
+                            # (served via cos-configuration-k8s, path: charms/planner-operator/cos_custom/grafana_dashboards)
+  webhook-gateway-operator/ # Juju charm: GitHub webhook gateway
+
+runner_grafana_dashboards/  # Grafana dashboards for runner VM host metrics
+                            # (served via cos-configuration-k8s, path: runner_grafana_dashboards)
+```
+
+## Observability: Grafana dashboards
+
+Dashboards in this repo are delivered to Grafana through
+[`cos-configuration-k8s`](https://charmhub.io/cos-configuration-k8s), which syncs
+JSON files from this Git repository and provisions them via the `grafana-dashboard`
+relation. Provisioned dashboards are **immutable** in Grafana regardless of user
+role — they cannot be edited or deleted through the UI.
+
+### Conventions
+
+| Directory | Purpose | `grafana_dashboards_path` config value |
+|---|---|---|
+| `charms/<charm>/cos_custom/grafana_dashboards/` | Dashboards for a specific charm's workload metrics | `charms/<charm>/cos_custom/grafana_dashboards` |
+| `runner_grafana_dashboards/` | Dashboards for runner VM host-level metrics (CPU, memory, disk, network) | `runner_grafana_dashboards` |
+
+Dashboard JSON files should use `__inputs` to declare the datasource (type `prometheus`).
+Setting `"editable": false` is recommended for clarity, but is not strictly required:
+dashboards delivered through `cos-configuration-k8s` are filesystem-provisioned and
+therefore read-only in Grafana regardless of the JSON flag. Metric names follow the
+[OpenTelemetry hostmetrics receiver](https://opentelemetry.io/docs/collector/components/#receiver)
+Prometheus naming convention (e.g. `system_cpu_time_seconds_total`).
