-# Platypush systemd service file.
-#
-# It is advised to install Platypush through a supported package manager or a
-# Platypush Docker container.
-#
-# In such case, the service file should be automatically installed and configured,
-# and Platypush can be started either via `[sudo] systemctl start platypush`
-# (privileged start, usually with a dedicated `platypush` user) or
-# `systemctl --user start platypush` if you want to run it through a generic user.
-#
-# In the first case, the working directory would usually be
-# `/var/lib/platypush`, and the configuration will be stored under `/etc/platypush`.
-#
-# You can however also copy this service configuration either to
-# `/etc/systemd/system/platypush.service` or
-# `~/.config/systemd/user/platypush.service`.
