 ## Overlap
 
-Product managers, engineers and support agents who write markdown for Confluence are the README's
-second audience. `mark` serves them as a publishing pipeline for a repository of documents; this
-package serves the four developer personas who embed a converter. The bot persona (generated
-markdown to ADF) is the one overlap: both turn markdown into Confluence content, but `mark` needs
-an account and the REST API, this package takes none (Goal 8). A user of `mark` who needs ADF can
-publish with `mark` and fetch the page as ADF through the Confluence REST API, which converts
-storage format to ADF; a user of this package who needs storage format has to go to that same API
-(`README.md` § Other ADF converters).
