Include additional examples

[peterschussheim]

Hi!

I was excited to try micro-analytics with my personal site, built using next.js and hosted on zeit now, however, after trying to get something working with my site, I am confused and not sure how this app is supposed to be used. Perhaps including more context in the example and add more examples would help.

I'd be happy to create a PR with examples if a bit of guidance was provided... :)

Thanks!
Peter
