 ```sh
 cd <path/to/your/project>
 npx ember-codemod-v1-to-v2 <arguments>
 ```
 
+> [!IMPORTANT]
+>
+> Before you run `ember-codemod-v1-to-v2`, I recommend that you address existing tech debts (one at a time). That is, treat the v2 migration as its own thing.
+>
+> Here are examples of what you may want to work on first:
+>
+> - [Meet prerequisites for v2 addon](https://github.com/embroider-build/embroider/blob/v4.3.1-%40embroider/addon-dev/docs/porting-addons-to-v2.md#part-3-prerequisites-for-v2-addon).
+> - [Un-pod v1 addon](https://github.com/ijlee2/ember-codemod-pod-to-octane).
+> - Update dependencies.
+> - Switch `npm` or `yarn` to `pnpm`.

 Step 2. Review the addon package.

-<sup>1. Before running `ember-codemod-v1-to-v2`, consider [meeting the prerequisites](https://github.com/embroider-build/embroider/blob/v1.8.3/PORTING-ADDONS-TO-V2.md#part-3-prerequisites-for-v2-addon). You can run [`ember-codemod-pod-to-octane`](https://github.com/ijlee2/ember-codemod-pod-to-octane) to un-pod a v1 addon.</sup>
