 <p>There are just two steps. First in your setup add the following:</p>
+
 ```csharp
 TestContext.Services.AddLocalization();
 ```
+
 <p>Then in your test code, when you need the localized string to compare, you write the following:</p>
+
 ```csharp
 var localizer = ctx.Services.GetService<IStringLocalizer<SharedStrings>>();
-  ```

 <p>Where SharedStrings.cs (you can name this anything you want) that has the resource files such as `SharedStrings.en.resx`</p>
