I’d be new to using Orthanc.
I install Orthanc on Ubuntu Desktop 18.10, I wonder how to install the Mysql plugin.
Instructions for MySQL are part of the Orthanc Book:
http://book.orthanc-server.com/plugins/mysql.html
If I had understood this documentation I would not ask for help. The documentation is very vague, does not explain anything right, if someone has a step by step I thank.
The documentation is as simple as it gets. If you cant understand it maybe you should hire someone who can.
