Good evening everyone.

I'm about to work on my first ZC installation.

Surfing around the forums and the ZC documentation, I noticed this 3 terms: MOD, ADDON and PLUGIN.
Because English is not my native language, I want to make sure what I understand correctly that, these are 3 different names for the same thing.

Is this correct or am I missing something?

Thanks in advance for your help.
