Is there any documentation on how to create a plugin? I found a guide (https://github.com/poctob/OSTEquipmentPlugin/wiki/Plugin-Development-Part-1-Getting-Started) that appears to be a little out of date. I created a plugin.php file with the name and details of the plugin, but when I go to install the plugin in osTicket, the yellow box with the install button appears but the name and version don't appear.I was hoping to find some sort of updated guide or documentation or even someone that could push me in the right direction.Thanks in advance!
