      It will be in this format:
      * * * * * php /path_to_pos_folder schedule:run >> /dev/null 2>&1
    2. Login into your Cpanel or direct admin or similar server management portal and Go into Cron Jobs or scheduler menu.
    3. In the “Add New Cron Job” section, select:
      minutes = *
      Hour = *
      Day = *
      Month = *
      Weekday = *
      Command = php /path_to_pos_folder schedule:run >> /dev/null 2>&1
      The command is same as the command displayed above except removing all the * before it.
    4. Click “Add New Cron Job” Button and it will be added.

NOTE: only one cron job is required for all features, don’t add it multiple times.
