Include additional examples

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

首先找到现有的 micro-analytics 示例和使用指南，然后将其与所请求的 Next.js 用例进行比较。完成的标准是文档提供更清晰的上下文以及解释如何使用该应用的其他示例；在选择具体示例之前，请先向维护者寻求指导。
