+
+-----------------------
+Creating the plist file
+-----------------------

+
+.. code-block:: none
+
+    which python
+
+Copy the output of that command.
+

+
+Paste the following and replace the following: 
+
+- all instances of :code:`username` with your Mac username 
+- :code:`path` with the path you copied earlier
+- :code:`instance-name` with your instance name:
+
+.. code-block:: none
+
+    <?xml version="1.0" encoding="UTF-8"?>
+    <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
+    <plist version="1.0">
+        <dict>
+            <key>Label</key>
+            <string>red</string>
+            <key>ProgramArguments</key>

+                <string>path</string>
+                <string>-O</string>
+                <string>-m</string>
+                <string>redbot</string>
+                <string>instance-name</string>
+                <string>--no-prompt</string>
+            </array>

+            <true/>
+            <key>KeepAlive</key>
+            <dict>
+                <key>SuccessfulExit</key>
+                <false/>
+            </dict>
+            <key>StandardOutPath</key>
+            <string>/tmp/red_out.log</string>
+            <key>StandardErrorPath</key>
+            <string>/tmp/red_err.log</string>

+            <key>InitGroups</key>
+            <true/>
+        </dict>
+    </plist>
+
+.. note::
+
+    You may add any additional arguments you need to add to the :code:`redbot` command by 
+    adding them to the end of the array under :code:`ProgramArguments`
+
+.. note::
+
+    Should you need to view the output from Red (for example: to find error messages that 
+    are output to the console to help with support), you can run :code:`nano /tmp/red_out.log` 
+    and :code:`nano /tmp/red_err.log` to do so
+
+Save and exit :code:`ctrl + O; enter; ctrl + x`
+
+-----------------
+Loading the plist
+-----------------
+
+Run the following:
+
+:code:`sudo launchctl load /Library/LaunchDaemons/red.plist`
+
+If you need to shutdown the bot, you can use the ``[p]shutdown`` command or
+type the following command in the terminal:
+
+:code:`sudo launchctl stop red`
