          ## 使用方法
          
          在 Clash 配置文件中添加：
          
          ```yaml
          rule-providers:
            reject:
              type: http
              behavior: domain
              url: "https://cdn.jsdelivr.net/gh/${{ github.repository }}@main/ruleset/yaml/reject.yaml"
              path: ./ruleset/reject.yaml
              interval: 86400
              
            proxy:
              type: http
              behavior: domain
              url: "https://cdn.jsdelivr.net/gh/${{ github.repository }}@main/ruleset/yaml/proxy.yaml"
              path: ./ruleset/proxy.yaml
              interval: 86400
              
            cncidr:
              type: http
              behavior: ipcidr
              url: "https://cdn.jsdelivr.net/gh/${{ github.repository }}@main/ruleset/yaml/cncidr.yaml"
              path: ./ruleset/cncidr.yaml
              interval: 86400
          
          rules:
            - RULE-SET,reject,REJECT
            - RULE-SET,proxy,PROXY
            - RULE-SET,cncidr,DIRECT
            - GEOIP,CN,DIRECT
            - MATCH,PROXY
          ```
          
          最后更新: $(date +'%Y-%m-%d %H:%M UTC')
          EOF
          
      - name: 提交更改
        run: |
          git config --local user.email "github-actions[bot]@users.noreply.github.com"
          git config --local user.name "github-actions[bot]"
          git add .
          git diff --cached --quiet || git commit -m "Update rules: $(date +'%Y-%m-%d')"
          git push
