| # Update Client | |
| Update Client is a reusable updater core that speaks the | |
| [Omaha 3.1 protocol](../../docs/updater/protocol_3_1.md). It powers the | |
| component and extension updaters, as well as the out-of-process updater in | |
| [chrome/updater](../../chrome/updater/README.md). | |
| The entry point to the library is `update_client.h`, and the comments in that | |
| file describe the library. |
