|  | = How Gerrit Works | 
|  |  | 
|  | To learn how Gerrit fits into and complements the developer workflow, consider | 
|  | a typical project. The following project contains a central source repository | 
|  | (_Authoritative Repository_) that serves as the authoritative version of the | 
|  | project's contents. | 
|  |  |

|  |  | 
|  | When implemented, Gerrit becomes the central source repository and introduces | 
|  | an additional concept: a store of _Pending Changes_. |

|  |  | 
|  | When Gerrit is configured as the central source repository, all code changes | 
|  | are sent to Pending Changes for others to review and discuss. When enough | 
|  | reviewers have approved a code change, you can submit the change to the code | 
|  | base. | 
|  |  | 
|  | In addition to the store of Pending Changes, Gerrit captures notes and comments | 
|  | made about each change. This enables you to review changes at your convenience | 
|  | or when a conversation about a change can't happen in person. In addition, | 
|  | notes and comments provide a history of each change (what was changed and why and | 
|  | who reviewed the change). | 
|  |  | 
|  | Like any repository hosting product, Gerrit provides a powerful | 
|  | link:access-control.html[access control model], which enables you to | 
|  | fine-tune access to your repository. |
