+### Style Guide
+
+We are currently migrating from JavaScript to TypeScript, so **All Source should be written in [ESM](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Modules)**
+
+That means only use nodejs `require` in js config file like `.eslintrc.js`
+
+You should always fully specify your import path extension,
+which means you should write `import * from "errors.ts"` for `errors.ts` file, do not write `import "errors.js"`.
