For example, if a tutorial exists but there is no coverage in Reference Guides, adding more content in a different format would benefit users.

 ## Gathering and validating supporting information
 
 Writing an effective doc that meets the needs of Gatsby users requires gathering information from various sources and applying those concepts to your original writing.
