      Welcome to the Platypush APT repository!

      Project homepage: https://platypush.tech
      Source code: https://git.platypush.tech/platypush/platypush
      Documentation / API reference: https://docs.platypush.tech

      You can use this APT repository to install Platypush on Debian, Ubuntu or any
      Debian-based distro.

      Steps:

      1. Add this repository's PGP key to your apt keyring
      ====================================================

      $ sudo wget -q -O \\\
          /etc/apt/trusted.gpg.d/platypush.asc \\\
          https://apt.platypush.tech/pubkey.txt

      2. Add the repository to your sources
      =====================================

      $ sudo wget -q -O \\\
          /etc/apt/sources.list.d/platypush.list \\\
          https://apt.platypush.tech/lists/platypush-<deb_version>-<branch>.list

      Where:

      - deb_version can be either *stable* (for the current Debian stable version) or
        *oldstable* (for the previous Debian stable version)
      - branch can be either *main* (for the latest releases) or *dev* (for a package
        that is always in sync with the git version)

      For example, to install the latest stable tags on Debian stable:

      $ sudo wget -q -O \\\
          /etc/apt/sources.list.d/platypush.list \\\
          https://apt.platypush.tech/lists/platypush-stable-main.list

      3. Update your repos
      ====================

      $ sudo apt update

      4. Install Platypush
      ====================

      $ sudo apt install platypush
