-2. Open the file `iri-registry.csv` located there and navigate to the bottom row of the file.
-3. In the next empty row, add the new IRI(s) as an increment from the last one. Also add your name, the date, and the associated issue number(s).
-4. Commit your changes directly to the IRI Registry Branch and push to origin.
-6. Now you can open a new branch off of `develop` to execute your work using the IRIs that you have registered.
