+  "Register a global command searchable by command palette.
+  `id` is defined as a global unique namespaced key :scope/command-name
+  `action` must be a zero arity function
+
+  Example:
+  ```clojure
+  (register
+   {:id :document/open-logseq-doc
+    :desc \"Document: open Logseq documents\"
+    :action (fn [] (js/window.open \"https://logseq.github.io/\"))})
+  ```
+
+  To add i18n support, prefix `id` with command and put that item in dict.
+  Example: {:zh-CN {:command.document/open-logseq-doc \"打开文档\"}}"
+  [{:keys [id] :as command}]
