 Other methods of the `IDistributedCache<BookCacheItem>` are same as ASP.NET Core's `IDistributedCache` interface, so you can refer [it's documentation](https://docs.microsoft.com/en-us/aspnet/core/performance/caching/distributed).
 
+## `IDistributedCache<TCacheItem, TCacheKey>` Interface
+
+`IDistributedCache<TCacheItem>` interface assumes that the type of your cache key is `string` (so, you need to manually convert your key to string if you need to use a different kind of cache key). `IDistributedCache<TCacheItem, TCacheKey>` can be used when your cache key type is not `string`.
+
+### Usage
+
+An example class to store an item in the cache:
+
+````csharp
+public class BookCacheItem
+{
+    public string Name { get; set; }
+
+    public float Price { get; set; }
+}
+````
+
+Example usage (assumes that your cache key type is `Guid`):
+
+````csharp
+public class BookService : ITransientDependency
+{
+    private readonly IDistributedCache<BookCacheItem, Guid> _cache;
+
+    public BookService(IDistributedCache<BookCacheItem, Guid> cache)
+    {
+        _cache = cache;
+    }
+
+    public async Task<BookCacheItem> GetAsync(Guid bookId)
+    {
+        return await _cache.GetOrAddAsync(
+            bookId, //Guid type used as the cache key
+            async () => await GetBookFromDatabaseAsync(bookId),
+            () => new DistributedCacheEntryOptions
+            {
+                AbsoluteExpiration = DateTimeOffset.Now.AddHours(1)
+            }
+        );
+    }
+    private Task<BookCacheItem> GetBookFromDatabaseAsync(Guid bookId)
+    {
+        //TODO: get from database
+    }
+}
+````
+
+* This sample service uses the `GetOrAddAsync()` method to get a book item from the cache.
+* Since cache explicitly implemented as using  `Guid` as cache key, `Guid` value passed to  `_cache_GetOrAddAsync()` method.
+
+`IDistributedCache<TCacheItem, TCacheKey>`  internally uses `ToString()` method of the key object to convert it to a string. If you need to use a complex object as the cache key, you need to override `ToString` method of your class.
+
+An example class that is used as a cache key:
+
+````csharp
+public class UserInOrganizationCacheKey
+{
+    public Guid UserId { get; set; }
+    
+    public Guid OrganizationId { get; set; }
+    
+    //Builds the cache key
+    public override string ToString()
+    {
+        return $"{UserId}_{OrganizationId}";
+    }
+}
+````
+
+Example usage:
+
+````csharp
+public class BookService : ITransientDependency
+{
+    private readonly IDistributedCache<UserCacheItem, UserInOrganizationCacheKey> _cache;
+
+    public BookService(
+        IDistributedCache<UserCacheItem, UserInOrganizationCacheKey> cache)
+    {
+        _cache = cache;
+    }
+    
+    ...
+}
+````

-## Project Status
-
-ABP is the **next generation** of the open source [ASP.NET Boilerplate](https://aspnetboilerplate.com/) framework. It's currently in preview stage and not ready to use in production. The documentation is still in progress and it is far from complete.
-
-For short-term and production level applications, it's suggested to use [ASP.NET Boilerplate](https://aspnetboilerplate.com/) framework which has rich feature set, mature, actively maintained and up-to-date.

 ## Getting Started
 
 Easiest way to start a new project with ABP is to use the startup templates:
 
-* [ASP.NET Core MVC (Razor Pages) UI Template](Getting-Started-AspNetCore-MVC-Template.md)
-* [Angular UI Template](Getting-Started-Angular-Template.md)
+* [ASP.NET Core MVC (Razor Pages) UI Startup Template](Getting-Started-AspNetCore-MVC-Template.md)
+* [Angular UI Startup Template](Getting-Started-Angular-Template.md)
 
 If you want to start from scratch (with an empty project) then manually install the ABP Framework and use the following tutorials:
