+    {date_heading} <h1>{entry_date format="%Y %m %d"}</h1> {/date_heading}
 
 The reason variable pairs have an opening and closing pair is because the information between the pairs can be shown or not shown if the criteria for each tag is met.
 
 In the case of the "date_heading" pair, for example, it only appears at a certain interval that you set (hourly, daily, weekly, monthly, etc.). By using a pair of variables, you can put HTML formatting between them that only gets shown when the interval is met. Otherwise, the chunk is not displayed.

+Commands to control and report on many of the core operations of ExpressionEngine can be issued via the terminal of your choice in the format of:
 
-`$ php system/ee/eecli.php hello`
+`$ php system/ee/eecli.php version`
 
-This will call `eecli` with a command of `hello`. This is the Hello World of ExpressionEngine commands, and will display:
+Assuming you're in the directory that contains the system folder, this will have `php` use ExpressionEngine's Command Line Interface tool, `eecli`, to run the `version` command.

-Commands can also request confirmation:
+This is the most basic of ExpressionEngine commands, and will display something similar to:

-yes
-That's good to hear!
+ExpressionEngine Version: 7.5.25

-Commands are also able to take interaction:
+`$ ./system/ee/eecli.php version`
 
-```
-$ php system/ee/eecli.php hello -i
+Commands can be interactive and ask you questions as they run. For example, this command will walk you through setting up the files and framework for a custom EE add-on:
 
-Hello world
-What's your name? Andy
-Pleasure to meet you, Andy!
 ```
+$ php system/ee/eecli.php make:addon
 
-WARN: **Important:** The CLI is available to every user that has SSH or terminal access to your site's webserver. It does not handle authorization inside ExpressionEngine and is relying on your server's authorization method instead.

+## Command Line Security
+
+WARN: **Important:** Unless disabled, the CLI is enabled by default and available to any person who has SSH or terminal access to your site's web server and who can run PHP scripts. The CLI does not handle authorization using ExpressionEngine's member system. It relies entirely on your server's authorization methods and simply treats a CLI user as a generic superuser.
+
+EE is available via the CLI even when EE is set to offline mode -- this mirrors a superadmin's access permissions in the control panel and makes it possible to perform maintenance and upgrades when a site is offline.
+
+If you want to disable CLI globally, this can be done by setting `cli_enabled` [configuration override](general/system-configuration-overrides.md#cli_enabled) to `n` or by running the following command:
+
+`$ php eecli.php config:config -c cli_enabled -v n` 
+
+(This would be a poor choice of command to use to test the CLI.)
+
+You can also enable and disable the CLI from [Security & Privacy Settings](control-panel/settings/security-privacy.md#enable-the-command-line-interface) in the Control Panel.
