 ### SetItem[Async] method now serializes string values
-Prior to v2 we bypassed the serialization of string values as it seemed a pointless as string can be stored directly. However, this led to some edge cases where nullable strings were being saved as the string `"null"`. Then when retrieved, instead of being null the value was `"null"`. By serializing strings this issue is taken care of.

However, this led to some edge cases where nullable strings were being saved as the string `"null"`. Then when retrieved, instead of being null the value was `"null"`. By serializing strings this issue is taken care of. 
 For those who wish to save raw string values, a new method `SetValueAsString[Async]` is available. This will save a string value without attempting to serialize it and will throw an exception if a null string is attempted to be saved.

+### Registering services as Singleton - Blazor WebAssembly **ONLY**
+99% of developers will want to register Blazored SessionStorage using the method described above. However, in some very specific scenarios,
+developers may have a need to register services as Singleton as apposed to Scoped. This is possible by using the following method:
+
+```csharp
+builder.Services.AddBlazoredSessionStorageAsSingleton();
+```
+
+**This method will not work with Blazor Server applications as Blazor's JS interop services are registered as Scoped and cannot be injected into Singletons.**
+
+
 ## Usage (Blazor WebAssembly)
 To use Blazored.SessionStorage in Blazor WebAssembly, inject the `ISessionStorageService` per the example below.

 ## Testing with bUnit
 This library provides test extensions for use with the [bUnit testing library](https://bunit.dev/). Using these test extensions will provide an in memory implementation which mimics session storage allowing more realistic testing of your components.
 
+### Installing
+
+To install the package add the following line to you csproj file replacing x.x.x with the latest version number (found at the top of this file):
+
+```
+<PackageReference Include="Blazored.SessionStorage.TestExtensions" Version="x.x.x" />
+```
+
+You can also install via the .NET CLI with the following command:
+
+```
+dotnet add package Blazored.SessionStorage.TestExtensions
+```
+
+If you're using Jetbrains Rider or Visual Studio you can also install via the built in NuGet package manager.
+
+### Usage example
+
 Below is an example test which uses these extensions. You can find an example project which shows this code in action in the samples folder.
