How to install a mod?
 

I have been searching and can't find it. How do I install a mod? I have itrader I want to install and I also want to install and arcade so if anyone has a link for one that is good with 4.0.5 let me know
Thank you very much!

To install the add ons you must read the read me file that comes with them because it varies for add on. But in a nut shell, the xml files should be uploaded at Plugins & Products->Manage Products->[Add/Import Product]->EITHER upload the XML file from your computer, here click the browse button, locate the mod.xml file that you have downloaded at your pc and then hit the Import button and you should be all set. If some add on will require additional files to uploaded, do so with Ftp at the appropriate folder as per the instructions.

Additionally have a look here as well. Hope it helps.

yes its not hard to install most mods, they will have some files that will be added sometimes to your server, and an xml file that you will upload in admincp/plugins and products

you should always add the files if they are needed first then install the product xml
after that you will have some new features and they will probably be added in settings/options

thats where you will control the new features your mod has installed
