 # Export to HTML
 
-After enabling the `print-site` plugin in your `mkdocs.yml`, you will have your entire site combined into a single page. That allows you to create a standalone HTML page: a single self-contained file that has all images, styling and scripts embedded. This means you could send a site as an email attachment, a use case common within companies where deploying static sites might be more involved.

-In order to create a self-contained, standalone HTML file from the print page, we will need to embed images, CSS and javascript using [data URLs](https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs). We can do this quite easily using the [htmlark](https://github.com/BitLooter/htmlark) python package:
+That allows you to create a standalone HTML page: a single self-contained file that has all images, styling and scripts embedded. This means you could send a site as an email attachment, a use case common within companies where deploying static sites might be more involved.
+This works because all the resources the page uses, such images, stylesheets (CSS) and interactive elements (javascript) are embedded into in a single HTML file using [data URLs](https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs).
 
+You can create a .html file export using your internet browser (f.e. save as > webpage, single page). You can also do this programmatically, for example using the [htmlark](https://github.com/BitLooter/htmlark) python package:
 
 ```shell
-pip install http html5lib requests
-pip install htmlark
+pip install htmlark[http,parsers]
 ```
 
 To create the export:
 
 ```shell
 mkdocs build
-
 cd site/
 
 # when mkdocs.yml has use_directory_urls: true (the default)
