Everything lives under Docs → Settings. Two decisions matter: which mode you run, and which base paths your docs live under. Everything else follows from those.
Single or multi product
Single mode puts every article under one base — /docs/article-slug/. Right for a site documenting one thing.
Multi mode gives every product its own home and base — /docs/product/ and /docs/product/article-slug/. Article slugs only need to be unique within a product, so two products can each have their own installation. You can also switch off per-product URLs to serve every product under one shared base.
Base paths
The base is the URL prefix docs live under — docs by default, or anything you choose per product in multi mode (for example help/product-name). The settings screen refuses duplicate or reserved bases, and when you change a base later, the old URLs keep working: the last ten bases per context are remembered and 301 to the new home automatically.
Categories
Categories group articles on a product home; they have no pages of their own — a category link scrolls to its section anchor. A category can be shared by several products, with an independent article order per product, set on the category edit screen.
The docs home page
In multi mode with per-product URLs there is no shared docs index — each product has its own home. If you want a landing page at /docs/, create a normal WordPress page there (the Doc Product Showcase block was made for it) and select it as the docs home page in settings. That page then also anchors the “Docs” breadcrumb on every article.
SEO out of the box
PimiDocs emits breadcrumbs with BreadcrumbList JSON-LD, canonical URLs for docs homes, and a sitemap provider. With Yoast SEO active, PimiDocs hands its breadcrumb trail and canonicals to Yoast so your pages carry exactly one of each, and keeps its URL-less taxonomies out of Yoast’s sitemap. No configuration needed — it detects Yoast and cooperates.
