Docs on using/ building prebidjs without adapters and use with prebid server (push gvlid's and tranform bid params function)

[spormeon]

So i had a chat with @patmmccann on adops slack about this. Its about putting up some docs for people on the ability to build prebidjs without the adapters that are needed for bidders that can use prebid server. Apparaently this is possible again now ( as it used to be, way back) but there are a few "quirks", i.e define gvlid in config, and set up the "transform bid params function". For the life of me i've done some searching and can't find any example anywhere on how to do this, which is the suggestion in effect. Is it possible to put up some docs, so people know/ can see how to do this. Pat suggested I write something, whihc happy to do, but i dont know what to do yet as got no examples etc. If someone can show me/ tell me, happy to write something, once know whats what adn how to do.
