 # CurrieTechnologies.Razor.Clipboard
+
 This package provides Blazor applications with access to the browser's [Clipboard API](https://developer.mozilla.org/en-US/docs/Web/API/Clipboard)
 
 ## This package is for Blazor Server Apps and Blazor WebAssembly Apps. [CurrieTechnologies.Blazor.Clipboard](https://github.com/Basaingeal/Blazor.Clipboard) is now deprecated.
 
 ## Usage
+
 1) In your Blazor app, add the `CurrieTechnologies.Razor.Clipboard` [NuGet package](https://www.nuget.org/packages/CurrieTechnologies.Razor.Clipboard/)
 
-    ```
+    ```sh
     Install-Package CurrieTechnologies.Razor.Clipboard
     ```
 
 2) In your Blazor app's `Startup.cs`, register the 'ClipboardService'.
 
-    ```
+    ```cs
     public void ConfigureServices(IServiceCollection services)
     {
         ...
         services.AddClipboard();
         ...
     }
     ```
+
 3) Add this script tag in  your root html file (Likely _Host.cshtml for Blazor Server Apps or index.html for Blazor WebAssembly Apps), right under the framework script tag. (i.e `<script src="_framework/blazor.server.js"></script>` for Blazor Server Apps or `<script src="_framework/blazor.webassembly.js"></script>` for Blazor WebAssembly Apps)
+
     ```html
     <script src="_content/CurrieTechnologies.Razor.Clipboard/clipboard.min.js"></script>
     ```
 
 4) Now you can inject the ClipboardService into any Blazor page and use it like this:
 
-    ```
+    ```razor
     @using CurrieTechnologies.Razor.Clipboard
     @inject ClipboardService clipboard
-    
+
     <input @bind="textValue" />
     <button @onclick="(async e => await clipboard.WriteTextAsync(textValue))">Copy To Clipboard</button>
     <button @onclick="(async e => textValue = await clipboard.ReadTextAsync())">Paste From Clipboard</button>
