Hi there,

I'm not sure if you still need help. But I guess it would be better to make yourself clear here, as in mind to be more specific? As "how do we start" can be answered by saying including the appropriate library before proceeding to any entity, architecture and so on.

Well, all the best. Is this a major project?
