+## External RPS collector
+
+The External RPS collector, like Skipper collector, is a simple wrapper around the Prometheus collector to
+make it easy to define an HPA for scaling based on the RPS measured for a given hostname. When
+[skipper](https://github.com/zalando/skipper) is used as the ingress
+implementation in your cluster everything should work automatically, in case another reverse proxy is used as ingress, like [Nginx](https://github.com/kubernetes/ingress-nginx) for example, its necessary to configure which prometheus metric should be used through `--external-rps-metric-name <metric-name>` flag. Assuming `skipper-ingress` is being used or the appropriate metric name is passed using the flag mentioned previously this collector provides the correct Prometheus queries out of the
+box so users don't have to define those manually.

+      target:
+        type: AverageValue
+        averageValue: "42"
+```
+### Multiple hostnames per metric
+
+This metric supports a relation of n:1 between hostnames and metrics. The way it works is the measured RPS is the sum of the RPS rate of each of the specified hostnames. This value is further modified by the weight parameter explained below.
+
+### Metric weighting based on backend
+
+There are ingress-controllers, like skipper-ingress, that supports sending traffic to different backends based on some kind of configuration, in case of skipper annotations
+present on the `Ingress` object, or weights on the RouteGroup backends. By
+default the number of replicas will be calculated based on the full traffic
+served by these components.  If however only the traffic being routed to
+a specific hostname should be used then the weight for the configured hostname(s) might be specified via the `weight` annotation `metric-config.external.<metric-name>.request-per-second/weight` for the metric being configured.
