Hey Everyone

I hope you can help.

I have just taken over a statamic site but have no idea it works.

Basically a friend was paying a firm a lot of money per month to manage their ppc campaigns . but have no tracking what so ever..... (unbelievable)

I want to add google tag manager to the store but i cant find for the life of me where to begin ?

i have logins for ramnode where the website is held but i cant see any data files .

Can anyone send me to the correct place to add a module to a store.

Be it a tool to add modules or a part of statamic ive not seen ?

Any help would be massively appreciated
