Because this is a book about programming with Minecraft and we want to focus on
learning the programming aspects of Minecraft, we have to assume a few things about
you the reader and what you already know:

1. You have a computer (a Raspberry Pi running Raspbian, a PC running Microsoft
Windows, or an Apple Mac running Mac OS X), which meets the minimum
requirements for running Minecraft, and is already set up and working.
2. You have a basic understanding of how to use your computer, such as using a
keyboard and a mouse, using the menu system to start programs, and using
application menus like File➪New➪Save.
3. You have a working connection to the Internet, and you know how to use a web
browser to download files from the Internet.
4. If you are using a PC or a Mac, you already have a Minecraft user ID and a working
copy of Minecraft installed.
5. You know how to play the Minecraft game, such as how to start it, how to move
around, how to choose items from the inventory, and how to create and delete
blocks in the world.
Because this is a book about programming Minecraft, we don’t assume you have any
prior knowledge about how to program. As you progress through your adventures, we
will lead you through the steps needed to learn programming.
