 _Docsify_ is a Single-Page Application library. It is **not** a static-site generator (though, hopefully this will change when Docsify version 5 comes out).
 
-_Jekyll_ and _Hugo_ are excellent options for static site generators. They can use themes suited to documentation and they can build off of a _docs_ directory. See more info in my [Jekyll Resources](https://michaelcurrin.github.io/dev-resources/resources/jekyll/). If you are interested in a Jekyll template that is built around presenting a docs site, see [jekyll-gh-actions-quickstart](https://github.com/MichaelCurrin/jekyll-gh-actions-quickstart).

 I find _Docsify_ light to add to a project and to use for new projects. So it is a great fit for me.
