<h3>WordPress Knowledge Base plugin</h3>
MinervaKB is flexible and powerful WordPress knowledge base plugin. It helps you to create a simple, yet powerful helpdesk or FAQ solution. You can add articles, organise them into topics and build a home page with AJAX live search for your customers to find their answers quickly. Use box or list layout with predefined design and styles. Dedicated search results page is also present. Using plugin as opposed to dedicated knowledge base theme also helps SEO of your main site greatly, as you don’t need to move your help content to subdomain.

Plugin is developer-friendly. We use many actions in templates and you can even copy template files to your theme and override plugin templates! To do so, create minerva-kb folder in the root of your theme and copy files from plugins/minervakb/lib/templates there. But this is optional, as you can modify templates via actions.
In case you need to use this plugin in language other than English, no localisation plugin or additional effort is required, as all the strings used on client-side are available to edit in options panel.
We tested MinervaKB Lite on many free and premium themes and it works surprisingly well with most of them. So it should work with any theme coded according to WordPress standards and respecting WordPress template hierarchy.
