How do I bind a custom repository to Statamic's service provider

1. Create a Custom Repository Class:
- Create a custom repository class that implements the appropriate contract, such as `Statamic\Contracts\Entries\EntryRepository`.
- This custom repository class can extend Statamic's default repository implementation or provide a completely new implementation.

2. Register the Custom Repository in the Service Provider:
- In your application's service provider (e.g., `AppServiceProvider`), override the `register` method.
- Use the `Statamic::repository()` method to bind your custom repository class to the appropriate contract.

Example:

php
   namespace App\Providers;

   use App\DatabaseEntryRepository;
   use Illuminate\Support\ServiceProvider;
   use Statamic\Contracts\Entries\EntryRepository;
   use Statamic\Statamic;

   class AppServiceProvider extends ServiceProvider
   {
       public function register()
       {
           Statamic::repository(
               EntryRepository::class,
               DatabaseEntryRepository::class
           );
       }
   }
   

In this example, we're binding the `DatabaseEntryRepository` class to the `EntryRepository` contract, effectively replacing Statamic's default entry repository implementation with our custom one.

3. Customize the Repository as Needed:
- Implement the necessary methods in your custom repository class to handle the desired functionality, such as fetching entries from a database instead of the default Stache.
- You can also override the `bindings` method in your custom repository to return different data classes (e.g., `DatabaseEntry` instead of the default `Entry` class).

4. Clear the Cache:
- After making changes to the repository bindings, make sure to clear the Statamic cache so that the new bindings take effect.

By following these steps, you can successfully bind your custom repository to Statamic's service provider, allowing Statamic to use your custom implementation for handling data, such as entries stored in a database instead of the default Stache.
