The "Orphan Black" series was released first. It contains five mostly stand-alone issues with each focusing on a single clone. They can be purchased as five single issues or as one trade paperback which will combine all five into book. Here's a link to digital versions of both. Here's a link to the print version of the trade.

The "Orphan Black:Helsinki" series was released second. It contains five issues that tell the story of the Helsinki protocol mentioned in the show. Currently, they can be purchased only as five single issues. The trade paperback is forthcoming. Here's a link to digital versions of the single issues. Here's a link to pre-order the physical trade.

I would suggest reading them in printed order because issue five of the first series sets up issue one of the second series.
