-## About
+### About
 X10D (pronounced *extend*), is a .NET package that provides extension methods for numerous types. The purpose of this library is to simplify a codebase by reducing the need for repeated code when performing common operations. Simplify your codebase. Take advantage of .NET. Use extension methods.
 
 *(I'm also [dogfooding](https://www.pcmag.com/encyclopedia/term/dogfooding) this library, so there's that.)*
 
-### What are extension methods?
-
-Extension methods are a clever .NET feature that augment existing types with new functionality. They are defined as
-static methods in a static class, and are called as if they were instance methods on the type they are extending. Take,
-for example, the following code:
-
-```csharp
-public static class Program
-{
-    public static void Main()
-    {
-        string str = "Hello, world!";
-        Console.WriteLine(str.Reverse());
-    }
-}
-
-public static class StringExtensions
-{
-    public static string Reverse(this string str)
-    {
-        char[] chars = str.ToCharArray();
-        Array.Reverse(chars);
-        return new string(chars);
-    }
-}
-```
-
-This will print `!dlrow ,olleH` to the console. The `Reverse` method is defined in the `StringExtensions` class, yet is
-called as if it were an instance method on the `str` variable, even though it's not.
-
-### Why use extension methods?
-
-Extension methods were introduced when LINQ was added to .NET. LINQ is a set of extension methods that provide a way to
-query, filter, and transform data. If you were to access LINQ's methods statically, you would have to write code like
-this:
-
-```csharp
-public static class Program
-{
-    public static void Main()
-    {
-        int[] numbers = { 1, 2, 3, 4, 5 };
-        IEnumerable<int> evenNumbers = Enumerable.Where(numbers, x => x % 2 == 0);
-        IEnumerable<int> doubledNumbers = Enumerable.Select(evenNumbers, x => x * 2);
-        int sum = Enumerable.Sum(doubledNumbers);
-        Console.WriteLine(sum);
-    }
-}
-```
-
-And if you wanted to one-line this, you'd have to write this:
-
-```csharp
-public static class Program
-{
-    public static void Main()
-    {
-        int[] numbers = { 1, 2, 3, 4, 5 };
-        Console.WriteLine(Enumerable.Sum(Enumerable.Select(Enumerable.Where(numbers, x => x % 2 == 0), x => x * 2)));
-    }
-}
-```
-
-This is a lot of code to write, and it's not very readable. The nested method calls make it incredibly difficult to
-follow. However, because LINQ is implemented as extension methods, you can write the following code instead:
-
-```csharp
-public static class Program
-{
-    public static void Main()
-    {
-        int[] numbers = { 1, 2, 3, 4, 5 };
-        Console.WriteLine(numbers.Where(x => x % 2 == 0).Select(x => x * 2).Sum());
-    }
-}
-```
-
-Because the methods are called as if they were instance methods on `IEnumerable<T>`, they can be chained together,
-making the code much more readable.
-
-X10D aims to provide these same benefits as LINQ, but for dozens of other types and for countless other use cases. See
-the [documentation](#documentation) for a complete breakdown of what's available.

 ## Installation
-
 ### NuGet installation
-
 ```ps
-Install-Package X10D -Version 4.0.0
+Install-Package X10D -Version 3.3.1
 ```
 
 ### Manual installation
-
 Download the [latest release](https://github.com/oliverbooth/X10D/releases/latest) from this repository and adding a direct assembly reference for your chosen platform.
 
-## Documentation
+### Unity installation
+For the Unity installation guide, refer to the [README.md in X10D.Unity](X10D.Unity/README.md).
 
-Documentation and the API reference is available at https://oliverbooth.github.io/X10D/index.html. *I'm sorry this took
-so long to get up and running. DocFX will be the death of me.*
+## Features
+I'm planning on writing complete and extensive documentation in the near future. As of this time, feel free to browse the source or the API using your favourite IDE.
+For those familiar with the 2.6.0 API, please read [CHANGELOG.md](CHANGELOG.md) for a complete list of changes. **3.0.0 is a major release and introduces many breaking changes.**
