-## Prerequisites
+## Get Started
 
-|                          .NET SDK                          |      Support       |

-## Usage
-
-Register the service in the DI container:
-
-```csharp
-// Program.cs
-
-using TailwindMerge.Extensions;
-
-var builder = WebApplication.CreateBuilder( args );
-
-// Add TailwindMerge to the container
-builder.Services.AddTailwindMerge();
-```
-

-Inject the service into component using one of the following approaches:
-
-```razor
-@* Page.razor *@
-
-@inject TwMerge TwMerge
-
-@TwMerge.Merge("px-2 py-1 bg-red hover:bg-dark-red", "p-3 bg-[#B91C1C]")
-@* → "hover:bg-dark-red p-3 bg-[#B91C1C]" *@
-```
-
-```csharp
-// Page.razor.cs
-
-[Inject] private TwMerge TwMerge {get; set; } = default!;
-
-TwMerge.Merge("px-2 py-1 bg-red hover:bg-dark-red", "p-3 bg-[#B91C1C]")
-// → "hover:bg-dark-red p-3 bg-[#B91C1C]"
