+        To generate a sha256 of your hash, you can use any of the following
+        commands. <b>DO NOT</b> send your mnemonic to a third-party service to
+        hash it, as it would no longer be secure. Make sure you've run <code>
+        unset HISTFILE</code> and <code>set +o history</code> to disable
+        persisting the mnemonic to your shell history.
