This D.Va guide was written by several Grandmaster and highly-ranked D.Va players. At 25+ pages in Google Docs, this is an incredibly detailed guide covering all aspects of D.Va. Note also that this guide was created for D.Va after the Missile rework. It may contain some outdated information, but it is one of the newer D.Va guides available.
This D.Va guide is more introductory, covering D.Va's basic abilities, role, and some character match-ups. At 14+ pages in Google Docs, it can hardly be considered "basic" though!

Want to hear about new resources? Suggest changes or updates? Berate me for writing or adding garbage? Come hang out in my Discord. It consists of a channel where I only post updates for this resource thing. It may eventually contain further channels. I don't really know how to work this thing oh god help I need an adult. "This thing" being social interaction, not Discord.
