You can download the latest version of Godot by visiting https://godotengine.org/ and clicking Download. This book is written for version 3.0. If the version you download has another number at the end (like 3.0.3), that's fine—this just means that it includes updates to version 3.0 that fix bugs or other issues.

On the download page, there are a few options that bear explaining. First, 32-bit versus 64-bit: this option depends on your operating system and your computer's processor. If you're not sure, you should choose the 64-bit version. You will also see a Mono Version. This is a version specially built to be used with the C# programming language. Don't download this one unless you plan to use C# with Godot. At the time of writing, C# support is still experimental, and is not recommended for beginners.

Double-click on the file you downloaded to unzip it, and you'll have the Godot application. Optionally, you can drag it to your Programs or Applications folder, if you have one. Double-click the application to launch it and you'll see Godot's Project Manager window.

There are a few other ways to get Godot on your computer besides downloading it from the Godot website. Note that there is no difference in functionality when installed this way. The following are merely alternatives for downloading the application:

• Steam: If you have an account on Steam, you can install Godot via the Steam desktop application. Search for Godot in the Steam store and follow the instructions to install it. You can launch Godot from the Steam application and it will even track your playtime.

• Package Managers: If you're using one of the following operating system package managers, you can install Godot via its normal install process. See the documentation for your package manager for details. Godot is available in these package managers:
