+![https://github.com/napi-rs/package-template/actions](https://github.com/napi-rs/package-template/workflows/CI/badge.svg)
+
+> Template project for writing node package with napi-rs.
+
+## Requirement
+
+- Install latest `Rust`
+- Install `NodeJS@8.9+` which supported `N-API`
+- Install `yarn@1.x`
+
+## Test in local
+
+- yarn
+- yarn build
+- yarn test
+
+And you will see:
+
+```bash
+$ ava --verbose
+
+  ✔ sync function from native code
+  ✔ sleep function from native code (201ms)
+  ─
+
+  2 tests passed
+✨  Done in 1.12s.
+```
+
+## Release package
+
+Ensure you have set you **NPM_TOKEN** in `Github` project setting.
+
+In `Settings -> Secrets`, add **NPM_TOKEN** into it.
+
+When you want release package:
+
+```
+yarn version [xxx]
+
+git push --follow-tags
+```
+
+Github actions will do the rest job for you.
