To begin editing an existing document, you must first clone two projects -- the master document framework project and the specific document project. Begin by cloning the master document as described in . Once complete, obtain a copy of the desired document by cloning its project. For example, to clone this document, Documentation Development Guide, from the public OpenPOWER Foundation git repository, use this command:$ git clone https://github.com/OpenPOWERFoundation/Docs-Template.git Cloning into 'Docs-Template'... Username for 'https://github.com': my_userid Password for 'https://my_userid@github.com': my_password remote: Counting objects: 62, done. remote: Compressing objects: 100% (10/10), done. remote: Total 62 (delta 2), reused 0 (delta 0), pack-reused 52 Unpacking objects: 100% (62/62), done. Checking connectivity... done. $ To build a specific document such as this guide, follow these steps from the directory where you just cloned:$ cd Docs-Template/template $ mvn clean [INFO] Scanning for projects...

Thus, the command mvn clean generate-sources would accomplish the same thing as the above sequence of commands. If all goes well, the generated pdf should be available in ~/Docs-Template/template/target/docbkx/webhelp/template-guide/. For assistance correcting commmon build failures, see . Projects may contain multiple documents. While specific documents can be built by executing a mvn clean generate-sources in the specific document directory, executing this command in the base project directory will build all projects identified in the <module> list in the top-level pom.xml file, known as the "Workgroup POM". You are now ready to begin making updates. Before diving deeply into new text, you may want to review to ensure that proper Work Product, Work Process, and security values are selected for your document.
