When you start the app and there is no entry for a given date, Diarly will use the template set in preferences to create a new entry for you automatically.
Daily prompt allows you to use special keywords:
$timewill insert the time when the entry was created
$weatherwill try to read your current location and based on that add the current weather forecast
$locationwill try to read your current location and insert it into the entry
$calendarwill try to read your today events from the Apple Calendar app and insert them
Diarly uses this template to create entry every time you start the app. If you want to use this template for other days you can use
cmd - ctrl - N shortcut.
