  description: >
    Self-hosted tasks and projects, shared with other people. Natural-language
    quick add in Danish and English, sub-tasks, labels, saved filters, board and
    calendar views, recurring tasks, reminders, comments and attachments. One
    binary with SQLite inside it — no database to set up. Set BASE_URL to the
    address you reach it on, point the SMTP settings at your mail server for
    invites and reminders, then start it and open the URL to create the first
    admin account.

  # Bumped whenever the variables below change. The panel keys its catalogue on
  # this: a manifest with new fields and an unchanged version is a manifest the
  # panel has no reason to re-read, so the fields never appear and the failure is
  # silent — the server's settings page simply does not offer them.
