DOC_CONTENTS="
You need to setup a configuraton file (/etc/motion/motion.conf) before
running motion for the first time.

If motion is built with the mysql or mariadb use flags then please make
sure to configure a matching database_type in the config file.

Motion runs by default under user motion and group motion:
- change this if needed in /etc/conf.d/motion
- or add users who need access to the output files to the motion group

To install motion as a service, use:
- rc-update add motion default # with OpenRC
- systemctl enable motion.service # with systemd
