You can enhance your automations by training your own classification models, a process that is both versatile and efficient. For detailed instructions on how to proceed, follow the steps from this page.

1. Open your Document Understanding<sup>TM</sup> modern project.
2. From the **Build** section, upload your documents and classify them:
   * To classify the documents automatically, follow the steps described in the [Out of the box document types](https://docs.uipath.com/document-understanding/automation-suite/2.2510/user-guide/classify-documents-automatically#out-of-the-box-document-types) procedure, on the **Classify document automatically** page.
   * To upload your document to a custom document type, follow the steps described in the [Custom document types](https://docs.uipath.com/document-understanding/automation-suite/2.2510/user-guide/classify-documents-automatically#custom-document-types) procedure, on the **Classify document automatically** page.
     :::note
     * The classifier will be trained using data from uploaded
     documents.
     * You need at least five documents for each document type to train a
     classifier.
     * You need at least two document types to train a classifier.

3. Once you've uploaded your documents, navigate to the **Measure** section to assess the performance of your classifier.
   :::tip
   * Check the
   recommendations on the right side of the window to improve your classifier's performance.
   * Only document types
   with at least five documents are displayed in the **Metrics** tab.
   * Each time you move a
   document to a different document type, the model is retrained.

4. Once you are satisfied with your classifier's metrics, proceed to the **Publish** section.
5. Create a new project version to include the classifier.
   1. Add a name for your project version.
   2. [Optional] Add a description for your project version.
   3. Select only **Classifier** from the **Models to include** drop-down list.
6. Deploy the project version, which includes the classifier, to use it in your automations.
   :::tip
   For more information on how to deploy a project version and automate your process, check the [Project version](https://docs.uipath.com/document-understanding/automation-suite/2.2510/user-guide/publish#project-version) section on the **Publish** page.
