# Overview

> Introduction to integrating and configuring document provider connections, OAuth setup, and using the StackOne Documents API and File Picker for unified file access

Most connectors need no setup beyond [linking an account](/embed/account-linking/overview) through the Hub.

Some providers need more: registering an OAuth application, granting admin consent, or enabling a feature on their side before StackOne can reach them. The guides here cover that provider-specific setup, and only apply to the providers that require it.

Where a provider offers configuration choices, your customer may see those during linking, and in some cases in the provider's own interface afterwards.
