+# Zig patch for OpenHarmony
+
+This project allow us to build zig that can build dynamic or use `zig cc` for OpenHarmony.
+
+For now, we use the default logic of `musl` to link libc or other logic. It may has some issues, but we need more examples or projects to test it.
+
+If you find some codes or logic need to adapt, you can submit a new issue or PR.
