# Sample Guide This folder demonstrates the expected structure and configuration files for a guide that can be transformed into HTML or PDF by the [doc_build](../README.md) infrastructure. | File/Folder | Description | | ---------------- | ----------- | | adoc/ | Folder containing AsciiDoc source for the guide. | | assets | Folder containing assets used in guide transformation. | | build.properties | Ant property file, specifying where the guide source lives, and where the doc_build infrastructure exists. | | build.xml | Ant build file. | | xml/ | Folder containing DocBook XML source for the guide. | Note: You normally only need one source for a guide, AsciiDoc or Docbook. AsciiDoc guides are transformed into DocBook with AsciiDoctor, and then processed as a DocBook guide. This sample guide provides both formats so you can test building HTML and PDF with either source format, and compare markup strategies.
