+## Features
+### Extension Methods for `IQueryable<T>`
+This package provides the extension methods `FirstOrNoneAsync`, `LastOrNoneAsync` and `SingleOrNoneAsync` for EF Core's `IQueryable<T>` objects.
+These are analogous to the ones provided by [`EntityFrameworkQueryableExtensions`].
+
+Example:
+```csharp
+using System;
+using Funcky.EntityFrameworkCore.Extensions;
+using Microsoft.EntityFrameworkCore;
+
+DbContext context;
+var firstPerson = await context.Set<Person>().FirstOrNoneAsync();
+firstPerson.AndThen(p => Console.WriteLine($"Hello {p.FirstName}!"));
+```
