+Install with Homebrew
+---------------------

+Moto is also available to install using `Homebrew`_, which makes it much easier

+
+Once Homebrew is installed, you can install Moto by running:
+
+.. code-block:: bash
+
+    brew install moto
+
+To make the Moto server start up automatically when you log into your computer,
+you can run:
+
+.. code-block:: bash
+
+    brew services start moto
