    - Correct icon path (usually `../../../../.icons/your-icon.svg`)
    - Proper tags that describe your module
 3. **Create tests for your module:**
-   - **New modules**: Create `.tftest.hcl` files and test with `terraform test`
-   - **Existing modules**: Keep `main.test.ts` files and test with `bun test`
+   - **New modules**: Create `*.tftest.hcl` files and test with `terraform test`
+   - **TypeScript tests**: Create `main.test.ts` files if your module runs scripts or has business logic that Terraform tests can't cover
    - **Both approaches** are supported
 4. **Add any scripts** or additional files your module needs
