+<para>
+With tarantool_deploy one can set up so that, during system boot,
+one or more instances of the tarantool_box server will start.
+Technically, tarantool_deploy will place instructions in <filename>/etc/init.d</filename>
+which will initiate tarantool_box with appropriate options and
+with settings that maximize resource usage.
+The root password is necessary. These options are available,
+as shown by <code>tarantool_deploy --help</code>:
+<programlisting>
+Tarantool deployment script: add more Tarantool instances.
+usage: tarantool_deploy.sh [options] &lt;instance&gt;
+
+  --prefix &lt;path&gt;       installation path (/usr)
+  --prefix_etc &lt;path&gt;   installation etc path (/etc)
+  --prefix_var &lt;path&gt;   installation var path (/var)
+
+  --status              display deployment status
+  --dry                 don't create anything, show commands
+
+  --debug               show commands
+  --yes                 don't prompt
+  --help                display this usage
+</programlisting>

+The default prefixes (<filename>/usr</filename> and <filename>/etc</filename> and <filename>/var</filename>) are appropriate
+if a Tarantool installation was done with default settings,
+for example tarantool_box should be in <filename>/usr/bin</filename>.
+The only necessary argument is the "instance", which is an
+arbitrary numeric identification formatted as digit.digit.
+The following is a sample run:
+<programlisting><prompt>$ </prompt>tarantool_deploy.sh 0.1
+tarantool_deploy.sh: About to deploy Tarantool instance 0.1.
+tarantool_deploy.sh: Continue? [n/y]
+y
+tarantool_deploy.sh: &gt;&gt;&gt; deploy instance 0.1
+tarantool_deploy.sh: &gt;&gt;&gt; updating deployment config
+tarantool_deploy.sh: done
+</programlisting>
