## Setup and Configuration

1. Navigate to the "Integrations" tab under "Settings".
2. Click on the "Connect GitHub" button.
   
   
3. You will be redirected to GitHub to authorize the WunderGraph Hub application.

You can either select ‘All repositories’ or ‘Select repositories’ to connect the repositories you want to connect to the subgraphs in WunderGraph Hub.
   
   
4. Once authorized, you will be redirected back to the WunderGraph Hub.
5. Now you can navigate to any of your graphs, click on the dropdown on the top left corner, select "Integrations" and select "Git".
   
   
6. You can now select the repositories you want to connect to the subgraphs in WunderGraph Hub.
7. Once you have selected the repositories, you can click on the "Save Mappings" button to connect the repositories to the subgraphs in WunderGraph Hub.
   
   This will create an initialization PRs in all the selected repositories with the respective subgraph schema.

## Pull Request Lifecycle

The GitHub integration automatically synchronizes pull request states with your schema proposal status, ensuring your development workflow stays aligned with your schema management process.

**Pull Request State Management:**

| State               | Behavior                                                                                                                                  |
|---------------------|-------------------------------------------------------------------------------------------------------------------------------------------|
| **Ready for Review**| When a proposal is created in opened state, a pull request is automatically created in “ready for review” state across all mapped repositories.|
| **Draft**           | When a proposal is moved to draft state, the pull request transitions to draft state.                                                       |
| **Closed**          | When the proposal is closed, the corresponding pull request is also closed.                                                               |
| **Reopened**        | If a closed proposal is reopened, the pull request is also reopened.                                                                       |

## How It Works

### Streamlined Development Workflow

The GitHub integration eliminates the friction between schema design and implementation by automatically creating branches in your mapped repositories whenever a schema proposal is made. This means developers can immediately start implementing changes without manual setup.

### Automatic Pull Request Creation

When a schema proposal is created in the hub, the integration automatically:
- Creates a new branch in the mapped repository  
- Stores the proposed schema files directly in the branch  
- Creates a pull request with the schema changes on new changes after creating a proposal or by opening the proposal.
