+# 🔒 Patterns – Automated OWASP CRS and Bad Bot Detection for Caddy, Nginx, and Apache  
 Automate the scraping of **OWASP Core Rule Set (CRS)** patterns and convert them into **Caddy, Nginx, and Apache** WAF configurations.  
 
-> This project helps protect web servers against common web attacks like **SQL Injection (SQLi)**, **XSS**, **RCE**, **LFI**, and more – automatically updated and deployed!  
+Additionally, **Bad Bot/User-Agent detection** is integrated to block malicious web crawlers and scrapers.

 ## 🚀 Project Overview  
 - **🎯 Goal**: Automate OWASP CRS rule collection and generate WAF configs for **Caddy, Nginx, and Apache**.  
 - **⚡ Automation**: GitHub Actions fetch rules **daily** and push updated configurations to the repository.  
-- **📄 Output**: WAF `.conf` files categorized by attack type (SQLi, XSS, LFI) for all supported web servers.  
+- **🤖 Bad Bot Blocking**: Block harmful bots by generating WAF rules from **public bot lists**.
