Emarshgaulin user research edits

[emarshgaulin]

Description

Used my previous experience in marketing and design to flesh out and add structure to the User Research article. My goals in editing were to provide additional clarity with headings, to add examples and context to the types of research, and to provide a simplified view of the research process.
