This book does not require the P4V software. Many of the concepts and best practices have standalone descriptions.
However, it is best to have an operational copy of P4V available for follow-along exploration. You can download P4V and server software for free from the Perforce website. A license is not required for the examples in the book. Appendix A, A Demo Server provides straightforward, step-by-step instructions for establishing your own server, a test repository, and the client software.
