Can I still carbonate a still cider?

[fishyblob]

I have a cider that has been sitting with a airlock for a little while. It tastes amazing, but I would like to carbonate it as it seems its missing some carbonization when I drink it. Would I have to add yeast again along with sugar to carbonate it? I have beer bottles and caps but have not really messed with carbonization much before. Thanks!

How long has it been aging? Is it still on the yeast bed?

Only been aging about a month and a half. Its got a little bit of sediment in the bottom.

I think it should be fine unless you've let it sit for a year or more.
