-### TypeScript support
+### TypeScript support and JSX code completion
 - Run the menu command `Project > Tools > ECMAScript > Generate TypeScript Project` from the godot editor to generate a TypeScript project
 - Run `tsc -w -p .` under your project folder in the terminal to compile scripts
 
+#### Code completion
+- Code completion in TSX will automatically work once the TypeScript project is generated by the above steps.
+- Code completion in JSX in VS Code is achieved by the property `"types": "./godot.d.ts"` in the generated package.json file of the TypeScript project. The `godot.d.ts` file can be generated alone via the `Project > Tools > ECMAScript > Generate TypeScript Declaration File` editor menu option and added to a `package.json` file manually to achieve this without a full TypeScript project.
+
 #### Example TypeScript Usage
 
 Make sure the file with extension '.tsx' so it can be compiled to a `.jsx` file then we can attach it to a node in godot editor.
