+# Caching
+
+Implementations of this feature provides predefined caching behaviour.
+
+Add this feature using `AddCaching()` extension;
+
+```csharp
+app.Features.AddCaching(...);
+```
+
+## Scoped Memory
+
+This feature implementation registers `Func<IMemoryCache>` factory with scoped
+`MemoryCache` implementation to provide request in-memory caching.
+
+```csharp
+c => c.ScopedMemory()
+```
