 # .NET YubiKey SDK
 
-This is a cross-platform, all encompassing SDK for the YubiKey aimed at large to mid-sized enterprise
-customers. This version is written against .NET Core, and will eventually include bindings to languages
-outside the direct .NET ecosystem.
+Enterprise-grade cross-platform SDK for YubiKey integration, built on .NET.
 
-## SDK Support
-The SDK is targetting net47, netstandard2.0 and netstandard2.1. This means the SDK can be loaded in NET Framework, NET6 and upwards.

+## Quick Start
+
+### Installation
+```bash
+dotnet add package Yubico.YubiKey
+```
+
+### Basic Usage
+```csharp
+using Yubico.YubiKey;
+
+// Chooses the first YubiKey found on the computer.
+IYubiKeyDevice? SampleChooseYubiKey()
+{
+    IEnumerable<IYubiKeyDevice> list = YubiKeyDevice.FindAll();
+    return list.First();
+}
+```

+### Building the Project
 
-### Building
+Prerequisites:
+1. Install required tools (see [Getting Started](./contributordocs/getting-started.md))
+2. Load `Yubico.NET.SDK.sln` into your IDE.
+3. Build solution
 
-Read the [Getting started](./contributordocs/getting-started.md) page to understand the prerequisites needed
-to build. Once those have been installed, you should be able to load the Yubico.NET.SDK.sln file and build.
+---
 
-Note that it is also possible to build the DocFX output at the same time as building the libraries. However,
-that is not done by default.
+## Connect with us
 
-If you want to build the DocFX output when you build the libraries using Visual Studio, open the Visual
-Studio solution file, and open `Build:Configuration Manager...`. In the resulting window, under
-`Active solution configuration:` is a drop-down menu. Select `ReleaseWithDocs`.
