+
+## Background
+
+For a little background on this factbook project from the humble author, 
+see the all-in-one page talk slides / notes titled [Turn the World Factbook into Open (Structured) Data](https://github.com/geraldb/talks/blob/master/factbook.md).
+
+Find some more notes on [query examples (and import instructions) for MongoDB](MONGO.md) 
+from another talk. Happy exploring the world with JavaScript Object Notation (JSON) datasets / documents.
+
+
+## Frequently Asked Questions (F.A.Qs) & Answers
+
+### Q: Why not just use the ISO country codes? Not a bug, a feature request.
+
+A: The factbook has many more entities / countries than ISO and sometimes with a different definition - 
+it's NOT an easy 1:1 mapping, see [Appendix D - Cross-Reference List of Country Data Codes](https://www.cia.gov/library/publications/the-world-factbook/appendix/appendix-d.html).
+
+### Q: I noticed that you've got Zambian data under ZA for the African region... It should be South African data...
+
+A: See why not ISO codes -  Uhhh... nevermind, I see it's stored under SF. Weird, but, ok :)
+
+### Q: Can you update the datasets? 
+
+A: Since November 2020 the datasets get auto-updated using / fetching the original
+online CIA World Factbook country profile web pages twice a month, that is,
+every 1st and 15th of every month. See the [GitHub Actions log](https://github.com/factbook/factbook/actions) for details.
