+## Bulk Operations
+You can execute bulk operations with `InsertMany`, `UpdateMany`, `DeleteMany` methods.
+
+Both providers `MongoDb` and `Ef Core` support bulk operations.
+
+### Customization
+
+If you have better logic or using an external library for bulk operations, you can override the logic via implementing `IMongoDbBulkOperationProvider` for MongoDb and `IEfCoreBulkOperationProvider` for Ef Core.
+
+- MongoDb Customization:
+
+```csharp
+public class MyCustomMongoDbBulkOperationProvider : IMongoDbBulkOperationProvider, ITransientDependency
+{
+    public async Task DeleteManyAsync<TEntity>(IMongoDbRepository<TEntity> repository,
+                                                IEnumerable<TEntity> entities,
+                                                bool autoSave,
+                                                CancellationToken cancellationToken)
+        where TEntity : class, IEntity
+    {
+        // Your logic here.
+    }
+
+    public async Task InsertManyAsync<TEntity>(IMongoDbRepository<TEntity> repository,
+                                                IEnumerable<TEntity> entities,
+                                                bool autoSave,
+                                                CancellationToken cancellationToken)
+        where TEntity : class, IEntity
+    {

 ## Custom Repositories
 
 Default generic repositories will be sufficient for most cases. However, you may need to create a custom repository class for your entity.
