## Puppeteer

The CLI based on [Puppeteer](https://github.com/GoogleChrome/puppeteer). But we don't want to depend on puppeteer locally, because puppeteer takes a long to install, it's easy to install failed. So we will find puppeteer in the local node_modules, if not found, find in the global node_modules, if still not found, we will install it globally, and you don't need to install it again next time.
