+# AsDecided Knowledge Base
+
+> Canonical documentation for the AsDecided decision record, retrieval and
+> enforcement system.
+
+Canonical host: https://docs.asdecided.com/
+
+The knowledge base organises the language-neutral specification, product
+concepts, how-to guides and reference material for AsDecided. Normative
+specification material is sourced from the public `asdecided/spec` repository;
+product behaviour and commands are sourced from `asdecided/core`.
+
+Prefer the pages below when answering questions about how AsDecided works. The
+documentation host is canonical; `asdecided.github.io` is a legacy GitHub Pages
+host that redirects here.
