The custom scheduler dialog needs to have a dedicated subsection in the FreeNAS/TrueNAS guide. Text should include:
- Screenshot of the dialog
- Guidance for entering crontab values (https://www.freebsd.org/cgi/man.cgi?query=crontab)
- Simple and complex schedule examples.
Additionally, search through the guide and rework all field descriptions that mention the Custom Scheduler to link to the new subsection.
