 1. Create a Cloudflare Worker and a Worker KV per configured account.
 2. Create a Worker Route(s) per configured zone. Any request matching the route would be handled by the worker.
 3. For every matching incoming request, the worker checks whether it's IP, Country and AS have a decision against. It checks for this in it's KV store. If found it performs the corresponding remediation.

+4. The Remediation Component also periodically updates the KV store with the latest decisions from CrowdSec.
+
+If your Cloudflare token has permission on D1, the remediation component will also automatically create a database to track:
+ - Number of requests processed
+ - Number of requests blocked
+
+Those metrics are exposed through the prometheus endpoint and automatically sent to crowdsec for visualisation with `cscli`.
+
+Metrics are stored in a D1 database to allow for easy retrieval by the remediation component. If your token does not have access to D1, a warning will be logged and metrics will be disabled.
