+## About
+
+<!-- A description of the package and where one can find more documentation -->
+
+Provides implementations for local and distributed in-memory cache. It stores and retrieves data in a fast and efficient way.
+
+## Key Features
+
+<!-- The key features of this package -->
+
+* A concrete implementation of the IMemoryCache interface, which represents a local in-memory cache that stores and retrieves data in a fast and efficient way
+* A distributed cache that supports higher scale-out than local cache
+* Expiration and eviction policies for its entries
+* Entry prioritization for when the cache size limit is exceeded and needs to be compacted by entry eviction
+* Track of cache statictics
+
+## How to Use
+
+<!-- A compelling example on how to use this package with code, as well as any specific guidelines for when to use the package -->
+
+Use Microsoft.Extensions.Caching.Memory over System.Runtime.Caching when working with ASP.NET Core as it provides better integration support. For example, IMemoryCache works natively with ASP.NET Core dependency injection.
+
+Local in-memory serialization:
+```csharp
+using Microsoft.Extensions.Caching.Memory;
+
+using MemoryCache cache = new(new MemoryCacheOptions());
+
+object valueToCache = new();
+string key = "key";
+
+using (ICacheEntry entry = cache.CreateEntry(key))
+{
+    // Entries are committed after they are disposed therefore it does not exist yet.
+    Console.WriteLine($"Exists: {cache.TryGetValue(key, out _)}\n");
+
+    entry.Value = valueToCache;
+    entry.SlidingExpiration = TimeSpan.FromSeconds(2);
+}
+
+bool exists = cache.TryGetValue(key, out object? cachedValue);
+Console.WriteLine($"Exists: {exists}" );
+Console.WriteLine($"cachedValue is valueToCache? {object.ReferenceEquals(cachedValue, valueToCache)}\n");
+
+Console.WriteLine("Wait for the sliding expiration...");
+Thread.Sleep(TimeSpan.FromSeconds(2));
+
+Console.WriteLine("Exists: " + cache.TryGetValue(key, out _));
+
+// You can also use the acceleration extensions to set and get entries
+string key2 = "key2";
+object value2 = new();
+
+cache.Set("key2", value2);
+
+object? cachedValue2 = cache.Get(key2);
+Console.WriteLine($"cachedValue2 is value2? {object.ReferenceEquals(cachedValue2, value2)}");
+```
