+# Example
+## Enabling AppSec WAF feature from crowdsec
+
+You mostly need to configure Crowdsec for this to work by enabling virtual patching and configuring some custom rules.
+In the example we use a whoami container protected by crowdsec with virtual patching enabled.
+
+The Traefik instance just needs to know where appsec engine is located
+```yaml
+  labels:
+      
+      - "traefik.http.middlewares.crowdsec-bar.plugin.bouncer.crowdsecappsecenabled=true"
+      - "traefik.http.middlewares.crowdsec-bar.plugin.bouncer.crowdsecappsechost=crowdsec:7422"
+```
+We can try to query normally the whoami server:
+```bash
+curl http://localhost:8000/foo
+```
+
+And then we verify that a malicious request will be blocked: 
+```bash
+curl http://localhost:8000/foo/rpc2
+```
+You should get a 403 on http://localhost:8000/foo/rpc2
+
+To play the demo environment run:
+```bash
+make run_appsec
+```
