# Document Understanding Process template
> **Document Understanding Process** is a fully functional UiPath® Studio project template based on a document processing flowchart. You can use it to get started with working on either a demo, or a large-scale implementation of Document UnderstandingTM.
## Overview
**Document Understanding Process** is a fully functional UiPath® Studio project template based on a document processing flowchart. You can use it to get started with working on either a demo, or a large-scale implementation of Document UnderstandingTM.
The process provides logging, exception handling, retry mechanisms, and all the methods that should be used in a Document Understanding workflow, out of the box.
## Framework
The Document Understanding Process template is preconfigured with a variety of basic document types, as well as classifiers and extractors, that are specific to an activity package. The template comes in the following project compatibility types:
* **Windows** – This framework uses the IntelligentOCR activity package, designed for Windows projects.
* **Cross-platform** – This framework uses the DocumentUnderstanding activity package, designed for Cross-platform projects.
Both template types are compatible with [modern projects](https://docs.uipath.com/document-understanding/automation-cloud/latest/user-guide/choosing-the-project-type), making the process template a best practice sample that you can adapt to your needs.

## Architecture
The process has an architecture decoupled from other connected automations:
* It does not matter where the files to be processed are coming from or what triggers the execution, this is the responsibility of an upstream process;
* It does not matter where the extracted information should be used, this is the responsibility of a downstream process.
The process has the same architecture for scenarios using both attended robots, and unattended robots running Document Understanding, that have human in the loop validation via Action Center.
Items are not processed in bulk. Instead, there is one job for each input file. A dispatcher is required for processing every item, but this flexible approach helps you get started, develop, debug, and scale Document Understanding processes.
## Supported project language types
The Document Understanding Process template only supports **Visual Basic** projects.
