-# kernel
+# feature[23] Shared Kernel
 
 [![build](https://github.com/feature23/kernel/actions/workflows/ci_build.yml/badge.svg)](https://github.com/feature23/kernel/actions/workflows/ci_build.yml)
+
+A library of reusable types for implementing Clean Architecture in .NET and ASP.NET Core applications, based heavily on the work of [Steve Smith](https://github.com/ardalis) in the following open-sourcee projects:
+- [ASP.NET Core Template](https://github.com/ardalis/CleanArchitecture)
+- [Shared Kernel](https://github.com/ardalis/Ardalis.SharedKernel)
+
+For the core functionality, only the `F23.Kernel` library is needed. This library provides types for events, results, query and command handlers, validation, and messaging. For smoother integration with ASP.NET Core, the `F23.Kernel.AspNetCore` library can be used for easily mapping between core result types and ASP.NET Core `IActionResult` and model state.
+
+> **WARNING:** This library is currently in a pre-release state, and breaking changes may occur before reaching version 1.0.
+
+## NuGet Installation
+### Core Package
+```powershell
+dotnet add package F23.Kernel
+```
+
+### ASP.NET Core Helper Package
+```powershell
+dotnet add package F23.Kernel.AspNetCore
+```
+
+## Examples
+
+### Query Handler
+```csharp
+class GetWeatherForecastQueryResult
+{
+    public required IReadOnlyList<WeatherForecast> Forecast { get; init; }
+}
+
+class GetWeatherForecastQuery : IQuery<GetWeatherForecastQueryResult>
+{
+    public int DaysIntoTheFuture { get; init; } = 5;
+}
+
+record WeatherForecast(DateOnly Date, int TemperatureC, string? Summary)
+{
+    public int TemperatureF => 32 + (int)(TemperatureC / 0.5556);
+}
+
+class GetWeatherForecastQueryHandler(IValidator<GetWeatherForecastQuery> validator, IWeatherForecastRepository repository)
+    : IQueryHandler<GetWeatherForecastQuery, GetWeatherForecastQueryResult>
+{
+    public async Task<Result<GetWeatherForecastQueryResult>> Handle(GetWeatherForecastQuery query, CancellationToken cancellationToken = default)
+    {
+        if (await validator.Validate(query, cancellationToken) is ValidationFailedResult failed)
+        {
+            return Result<GetWeatherForecastQueryResult>.ValidationFailed(failed.Errors);
+        }
+
+        var forecast = await repository.GetForecast(query.DaysIntoTheFuture, cancellationToken);
+
+        var result = new GetWeatherForecastQueryResult
+        {
+            Forecast = forecast
+        };
+
+        return Result<GetWeatherForecastQueryResult>.Success(result);
+    }
+}
+```
+
+#### Program.cs
+```csharp
+builder.Services.RegisterQueryHandler<GetWeatherForecastQuery, GetWeatherForecastQueryResult, GetWeatherForecastQueryHandler>();
+
+// Other code omitted for brevity
+
+app.MapGet("/weatherforecast", async (IQueryHandler<GetWeatherForecastQuery, GetWeatherForecastQueryResult> queryHandler) =>
+    {
+        var result = await queryHandler.Handle(new GetWeatherForecastQuery());
+
+        return result.ToMinimalApiResult();
+    })
+    .WithName("GetWeatherForecast")
+    .WithOpenApi();
+```
