[Feature request] embed docsify on third party site

Docsify is great but I find I can only use it in a dedicated website. It would be more flexible if docsify can be embedded on other sites. Although it's possible in theory but in practice I found that it doesn't work well.

For example: I wanted to use docsify to generate the documentation on this site:

https://uis-azr-test-fusionapi-eus1.portal.azure-api.net/user-guide-2

When I embedded docsify into the html if found that it completely changed the layout of my website. I think one of the reasons is that it modified the nav of the website.

I ended up using flatdoc which doesn't have the same features but it's less intrusive on the host website.
