Note that both themes are made to be child themes of the main theme of your website! They only add one new page template that is to be used when you publish your docs from Helpinator. That means you need to manually alter "styles.css" file and change "twentynineteen" (default WordPress theme) to the name of your main theme (if it is different). You need to select "HelpinatorDocPageTemplate" as page template when publishing your online documentation from Helpinator.
Helpinator Quick Publish plugin
WordPress XML-RPC is pretty slow when you need to publish a lot of content items at once. In fact you can drink a cup of coffee while your project is being published. This plugin extends Wordpress XML-RPC API to speed up publishing of Helpinator projects and also fixes API bug that prevents already published images from being updated.
How to get the plugin?
Open admin dashboard of your WordPress site.
Open "Plugins" section.
Click "Add new".
Enter "Helpinator" into the search field.
Click "Install now" in the "Helpinator Quick Publish" box.
