 ## Using Entity Framework for the Server-Side Session Store
 
-To use the EF session store, install the `Duende.BFF.EntityFramework` NuGet package and register it by calling `AddEntityFrameworkServerSideSessions`, like this:
+To use the EF session store, install the `Duende.BFF.EntityFramework` NuGet package:

+Next, you can register the session store by calling `AddEntityFrameworkServerSideSessions`, like this:
 
 ```csharp
 var cn = _configuration.GetConnectionString("db");
-        
+
 builder.Services.AddBff()
     .AddEntityFrameworkServerSideSessions(options=> 
     {
         options.UseSqlServer(cn);        
     });
 ```
+
 The method of `AddEntityFrameworkServerSideSessions` registers the `SessionDbContext` along with a `UserSessionStore` as transient dependencies.
 
 For developers looking to take advantage of DbContext pooling or have more fine-grained control over their DbContext creation registration and creation process, you can use the `AddEntityFrameworkServerSideSessionsServices` method instead. This method registers all the required services for server-side session except for the `SessionDbContext`, which will now be managed by the DbContext pooling mechanism.
