-- Include source files only — do not include `node_modules`, `.next`, or other build artifacts.
-- Zip the outermost project folder itself (right-click the folder → compress), not files selected from inside it.
-- If you import only one file from a nested folder, include one unchanged source file from another top-level folder as a path anchor. For example, include both `app/page.tsx` and `components/widgets/chart.tsx` so the component keeps its full `components/widgets/...` path.
-- Import merges with the existing project and overwrites any files that share the same path.
+- Include source files only. `node_modules`, `.next`, and other build artifacts are ignored automatically.
+- The ZIP replaces the existing project. Files you leave out are removed from the new version.
+- If the ZIP contains one wrapper folder, Teable strips that folder. You can compress the outermost project folder directly.
+- The imported project must include `package.json` at the project root.
 - A root `.env` file in the ZIP is read into the app's **Secrets**. Other `.env*` variants, such as `.env.local`, are ignored.
