About the Book
Most tutorials just settle with teaching you how to deploy your Rails apps to Heroku. This is unfortunate, since you're missing out on so many things when you don't know how to setup your own server from scratch.
This book will guide you as you take your first steps into deploying your projects on bare VPSs.
Half of the book is free to download and read online; it covers just enough for you to deploy your app.
