What you need for this book 

This book can, of course, be read without a computer at hand, in which case, you need nothing more than the book itself. However, to follow the examples in the book, you need a compiler of Perl 6, which you can download from  http://rakudo.org/how-to-get-rakudo/ (more details on installing it are in Chapter 1, What is Perl 6?). The Rakudo Perl 6 compiler works on a variety of platforms--Windows, macOS, and Linux. You will also need your favorite text editor to write programs in.
