This includes:

• The different form factors and their differences
• How to use the Source Generator
• How to use the CLI
• The configuration files
  • How the AdditionalFiles work (and what the user has to do)
  • How the .editorconfig option(s) work (and what the user has to do to use them)
• Configuring the Scraper
  • All JSON configuration options
  • What each XML mod does
    • What additional configuration options each XML mod takes (i.e. the Vulkan-specific mods taking a link to the Vulkan XML specification in the modOptions)
• Configuring the Emitter (if necessary?)
• Configuring the Overloader (if necessary?)
• Perhaps more?
