Chainquery resource - getting started, query samples

[tzarebczan]

Based on the conversation in https://spectrum.chat/lbry?thread=21e8fd79-3025-4738-a903-991c4232d9fd, would be good to have a lbry.tech resource on how to get started with chainquery, what the data model looks like, how to construct queries, etc.

@tiger5226 and @skhameneh Would either or both of you be interested in putting together an article for .tech?

Sure, @tzarebczan is there a guide anywhere on how to create a .tech article?

Just drop it into the resources folder and add a link in https://github.com/lbryio/lbry.tech/blob/master/documents/resources.md
