Facebook & Twitter

Very general question this… I’m not really an FB or Twitter user but am starting to develop a Foundation website that requires the customer’s Facebook & Twitter feeds to be displayed. I’ve spent some time researching how to do this but have to admit I’m really confused about how to go about it.

Can any kind soul please point me in the right direction? Surely, it can’t be that difficult can it? I’ve tried following the instructions as provided by here, for example, but it simply doesn’t seem to work for me.

Sorry - please ignore - just realised it was a Safari extension I use that was blocking things. Cost me a lot of time that.
