### Install

## Calendar Subscription

If you'd rather see your deadlines alongside the rest of your schedule, you can
subscribe to them from any calendar app. This is read-only — you can't create or
complete tasks from your calendar — but it puts your pending deadlines, and what
each one is staked at, on your calendar. See the
[Calendar Feed integration](./integrations/calendar.md) for setup.
