+## Command Queue
+
+In order to avoid race conditions the object SHOULD have a `cmd` property.
+This object is defined as follows
+
+```ts
+window.nostr.cmd: (() => void)[]
+```
+
+Browsers or extensions SHOULD invoke all callbacks queued once it has finished loading.
+After that it should shadow the `push` method on `cmd`
+to immediately invoke subsequent queues
+
+This allows consumers to queue up calls to the NIP-07 providers even before
+it is present.
+
+### Examples
+
+Queue a command
+
+```js
+window.nostr = window.nostr || { cmd: [] };
+
+window.nostr.cmd.push(() => {
+  const pk = window.nostr.getPublicKey();
+  // do something with pk
+});
+```
+
