+# CrowdSec Configuration for Docker Compose
+
+This directory contains CrowdSec configuration files for testing the HAProxy SPOA bouncer with AppSec.
+
+## Collections
+
+The following collections are required for AppSec functionality:
+
+- `crowdsecurity/appsec-virtual-patching` - Protection against known vulnerabilities
+- `crowdsecurity/appsec-generic-rules` - Generic attack vector detection
+
+These collections are automatically installed when the CrowdSec container starts via the `COLLECTIONS` environment variable in `docker-compose.yaml`.
+
+## Acquisitions
+
+The `acquisitions/appsec.yaml` file configures the AppSec Component to listen on port 7422 for HTTP request validation.
+
+## Manual Collection Installation
+
+If you need to manually install collections (e.g., when persisting `/etc/crowdsec/` on the host):
+
+```bash
+docker exec -it crowdsec cscli collections install crowdsecurity/appsec-virtual-patching crowdsecurity/appsec-generic-rules
+```
+
+## AppSec Component
+
+The AppSec Component listens on `0.0.0.0:7422` and can be accessed from other containers in the Docker network at `crowdsec:7422`.
