+
+You must install [zed-extension](https://github.com/zed-industries/zed/tree/main/crates/extension_cli) cli first.
+
+hello你好
+
+## Release
+
+1. Update the version in `Cargo.toml` and `extension.toml`.
+2. Commit with message `Release vX.Y.Z`.
+3. Create git tag `vX.Y.Z` and push.
+4. Then GitHub Actions will automatically create a release PR to [zed-extensions](https://github.com/zed-industries/extensions/pulls).
