## Upload documents

After successfully creating your project, you can upload your documents from the **Build** section.

1. Open your project.
2. Drag and drop the first batch of your sample documents in the **Upload sample documents** section.
   :::tip
   You can use the suggestions from the **Recommendations** sections. These suggestions will guide you through the process.
   :::

The uploaded files are automatically processed (uploaded, digitized, classified, annotated).

3. Upload the next batch of your sample documents by selecting **Upload**.
   :::tip
   You can check the **Recommendations** sections for suggestions on what more is useful to upload. For example, if there are too few **utility_bills** documents, a suggestion is displayed: **utility_bills** has too few samples. Add at least 150 documents for an optimal data set size. There are two types of recommendations, one for classification and one for extraction models.

4. Review the uploaded documents.
   1. Expand the needed section (for example, **invoices**, **receipts**).
   2. Select a document name.
   3. Check if the **Document type** filled in automatically is correct. You can change the document type using the drop-down list.

## Import datasets

Once you have an exported dataset, you can import it into a different project. For more information on how to export datasets, check the [Export](https://docs.uipath.com/document-understanding/automation-cloud/latest/user-guide/migrating-existing-modern-projects#export) section from the **Publish** page.

If there are any errors during import, an error message is displayed.

1. Navigate to and open the project into which you want to import data.
2. Select **Add document type** and create a new custom document type.
   :::note
   You can only import zip datasets directly in a document type.
