To get started, go to the Account tab and connect your Google, Apple, or Outlook calendar.
To create your first rule:
- Select a Source calendar. This is the calendar Stellar will monitor for events.
- Select a Scope: All events copies every event; Opt-in only copies only events you tag with
#stellar-copy or #stellar-busy.
- Choose a Default: Copy copies full event details; Busy replaces details with "Busy". You can override this per-event with
#stellar-copy or #stellar-busy in any event description.
- Optionally add a #tag filter to only sync events containing that hashtag.
- Select a Destination calendar. This is the calendar Stellar will copy events to.
- Click Add.
Stellar will immediately begin syncing your events and will keep the destination up to date as events change.
To stop syncing and remove copied events, click Edit then Delete on the rule.
