How to get started
Getting Started with PostBooks explains how to download the software, and particularly the difference between the all-in-one PostBooks installer and the different components available for advanced users who want to set things up their own way.
You might also want to review the full online Reference Guide (also available for sale as a PDF), or a detailed comparison of the PostBooks, Standard, and Manufacturing Editions of xTuple.
