The help centre — From table to site
Point the help centre at the columns that matter: which field is the article body, which column says an article is published, and — optionally — which groups articles into categories. The record's name is the article's title. Pick a slug and the site answers at /kb/that-slug, wearing the logo and colours from Settings → Branding.
Readers get a search box above the index, running the same matcher the chat widget answers with — same stemming, same scoring — so the two doors rank the same article the same way. It needs at least six characters: type fewer and the page says so and shows you everything, rather than handing back a result set that quietly matched almost every article.
Setup is honest about the difference between "published" and "publishes something": a centre that is switched on but cannot read a body column says so on its own settings page, rather than serving an empty site.
This is the public site, wearing your branding. The categories are just a column on the articles table.
