+# Docker 镜像测速
+
+## Why
+
+因为众所周知的原因，国内访问 Docker Hub 的速度非常慢。广大热心网友贡献了大量的镜像加速服务，但是速度参差不齐。
+
+
+所以该项目旨在罗列互联网上分享的镜像地址，并生成测速结果。
+
+> [!WARNING] 注意
+> 测速利用 GitHub Actions，服务器托管在国外，因此测速结果中的速度快不代表国内拉取快。
+>
+
+本项目尽量保证罗列的镜像地址可用。
+
+## 测速结果
+
+| Registry | Status | Speed | Time |
+|----------|--------|-------|------|
+| hub.rat.dev | | | |
+| docker.m.daocloud.io | | | |
