Connections is 63% percent translated in Arabic. The quality of the translation is unknown since this was freely contributed. You can always help to improve it and earn a free Pro Pack.
There is no special process to deploying Connection in Arabic. Make sure your WordPress installation is set to Arabic and install Connections like you would any other plugin.
Purchasing cMap, go to the product page, add it to the cart and checkout. Pretty standard, no special process. The template does have a few strings that you’ll need to translate, but that can be done easily in the Template Customizer for cMap.
Hope that helps!
