+
+Completion is supported via asyncomplete, for links to other notes. To enable
+this, include:
+
+>vim
+    autocmd User asyncomplete_setup {
+        asyncomplete#register_source(
+            asyncomplete#sources#mbnotes#get_source_options({ 'priority': 9 })
+        )
+    }
+<
+
+This completion support depends on ripgrep being installed.
