# Connect: Integrating Your Data Sources

The graph's value is proportional to the data flowing into it. The LCG supports multiple data source types, with email and operating systems being the most common starting point, most logistics context lives in inboxes while operational steps live in operating systems.

#### Document and System Feeds

Documents can be ingested directly via PDFs, spreadsheets, and images from your WMS, TMS, or other systems. Every source passes through the same pipeline, making integration source-agnostic.

#### Email Connectors

The system provides native connectors for Gmail and Outlook / Microsoft 365, including shared mailbox support. Once connected via OAuth, the system continuously syncs new messages using incremental cursors. Users connect once, and the graph stays current automatically.

#### Full Provenance

Every entity in the graph traces back to its origin. When an agent answers "what are the charges on this shipment?", it can also tell you which document and which email thread those charges came from.
