+## Codeowners and PR Guidance
+
+As the creator of a PR, the assignment of a reviewer can be unclear. For most PRs, feel free to select a few members of the core development team. These individuals scan each repository on a regular basis as well and may provide his/her review even if not originally included as a selected reviewer. 
+
+Sometimes, the development of a function or a vignette falls under a specific-topic, e.g. labs or PK/PD. Please ensure you include an appropriate reviewer if you are modifying files that rely on domain-expertise. We try to maintain an active list for domain-specific topics that will automatically tag an appropriate reviewer using our `CODEOWNERS` file, located in the `.github` folder. If you are interested in being a codeowner, reach out to the development team.

 # So much Red Tape!
 
 The `{admiral}` development team is aware and sympathetic to the great many checks, processes and documents needed to work through in order to do a compliant Pull Request. The `task-list-completed` GitHub workflow was created to help reduce this burden on contributors by providing a standardized checklist that compiles information from the Pull Request Review Guidance, [Programming Strategy](programming_strategy.html) and [Development Process](development_process.html) vignettes.
