Just me, on one computer

The simplest setup: Zomello on your Windows or Linux computer, nothing else.

1. Install Zomello from the latest release (Quick start has the details).
2. Make sections for the parts of your life: + Section > Work, Home, Personal.
3. Make a board in each (the + next to a section's name).
4. Set yourself as Me in Settings > People (the welcome guide does this), so Home and My Tasks show your tasks.
5. Turn on reminders: Settings > Reminders, then Settings > Desktop app > Keep running in the tray and Start Zomello when I log in, so reminders arrive even when the window is closed.
6. Start each day on Home: late, due today, next 7 days.

Your data: it's all on this computer, with a backup every 30 minutes (Data and backups). Copy the data folder now and then to a USB stick or cloud drive for extra safety.

Later: add your phone with My computer and my phone.
