          ## 使用方法
          
          在 Clash 配置文件中添加：
          
          \`\`\`yaml
          rule-providers:
          EOF
          
          # 定义规则类型
          declare -A rule_types=(
            ["reject"]="domain"
            ["icloud"]="domain"
            ["apple"]="domain"
            ["google"]="domain"
            ["proxy"]="domain"
            ["direct"]="domain"
            ["private"]="domain"
            ["telegramcidr"]="ipcidr"
            ["cncidr"]="ipcidr"
            ["lancidr"]="ipcidr"
            ["applications"]="classical"
          )
          
          # 生成 rule-providers
          for rule in reject icloud apple google proxy direct private telegramcidr cncidr lancidr applications; do
            cat >> README.md << EOF
            ${rule}:
              type: http
              behavior: ${rule_types[$rule]}
              url: "https://git.nvme.cc/${{ github.repository }}/raw/branch/main/ruleset/yaml/${rule}.yaml"
              path: ./ruleset/${rule}.yaml
              interval: 86400
              
          EOF
          done
          
          # 添加 rules 部分
          cat >> README.md << EOF
          rules:
            - RULE-SET,applications,DIRECT
            - RULE-SET,private,DIRECT
            - RULE-SET,reject,REJECT
            - RULE-SET,icloud,DIRECT
            - RULE-SET,apple,DIRECT
            - RULE-SET,google,PROXY

            - RULE-SET,telegramcidr,PROXY
            - RULE-SET,lancidr,DIRECT
            - RULE-SET,cncidr,DIRECT
            - GEOIP,LAN,DIRECT
            - GEOIP,CN,DIRECT
            - MATCH,PROXY
          \`\`\`
          
          最后更新: $(TZ='Asia/Shanghai' date +'%Y-%m-%d %H:%M')
          EOF
          
      - name: 提交更改
        run: |
          git config --local user.email "gitea-actions[bot]@users.noreply.nvme.cc"
          git config --local user.name "gitea-actions[bot]"
          git add .
          git diff --cached --quiet || git commit -m "Update rules: $(TZ=Asia/Shanghai date +'%Y-%m-%d %H:%M:%S')"
          git push
