-**IMPORTANT:** Please take note of the `run` part, where each directory is listed:
-
-```bash
-for section in [DIRECTORY1] [DIRECTORY2] [DIRECTORY3] [DIRECTORY4]; do
-```
 
 This is different from the single site workflow. If you move from single site to multisite you need to updated the entire script -- it is not sufficient to just list the paths!
