I want to fix a few issues I've found in the guidance and add my own content, where are the word editable versions of the guidance and the HOL. I see PDF and XPS but can't find the .DOCx versions

Allen, the master documents (DOCX, PPTX, etc.) are available to all ALM Rangers. If you wish to add your content you can persue one of the following options:

1. Submit your ideas in UserVoice using the Rangers project category tag.
2. Work with this team to get your content suggestions reviewed and considered for inclusion in a subsequent update.
3. Join the ALM Rangers and this team. See Understanding the Visual Studio ALM Rangers for details on joining.
