+# Object Pool
+
+This directory contains sources for [`Microsoft.Extensions.ObjectPool`](https://www.nuget.org/packages/Microsoft.Extensions.ObjectPool). This package provides types that enable object reuse. You can find additional information in the [ASP.NET Core Documentation](https://docs.microsoft.com/aspnet/core/performance/objectpool).
+
+## Description
+
+This project contains abstractions and default implementations for pooling objects. Commonly used types include:
+
+`ObjectPool<T>` - This represents a pool of objects. This is used to get and return pooled objects.
+`IPooledObjectPolicy<T>` - This policy defines how pooled objects are created and returned.
+`ObjectPoolProvider` - This represents a provider of `ObjectPool<T>`. This is used to create object pools based on an `IPooledObjectPolicy<T>`.
+
+
+For a full list of the types defined in this project, see [the namespace documentation](https://docs.microsoft.com/dotnet/api/microsoft.extensions.objectpool).
