 ## Build and release process
 
-This theme is subject to a CI driven build and release process common for software development. During the release build, all necessary assets are automatically built by [gulp](https://gulpjs.com/) and bundled in a release tarball. You can download the latest release from the GitHub [release page](https://github.com/thegeeklab/hugo-geekdoc/releases).

 ## Install requirements
 
-You need a recent version of Hugo for local builds and previews of sites that use Geekdoc. As we are using [gulp](https://gulpjs.com/) as pre-processor the normal version of Hugo is sufficient. If you prefer the extended version of Hugo anyway this will work as well. For comprehensive Hugo documentation, see [gohugo.io](https://gohugo.io/documentation/).
