Aaron van Wirdum has a nice tweet thread with the articles he's written about taproot, all of which are very approachable. https://twitter.com/AaronvanW/status/1403701310352920576
If you want more after reading that, @bitcoinoptech tracked almost every stage of taproot's development, writing about it over fifty times as listed here: https://bitcoinops.org/en/topics/taproot/ (and we're not done yet: now we get to write about what people actually build with taproot!)
