 Active Help is a framework provided by Cobra which allows a program to define messages (hints, warnings, etc) that will be printed during program usage.  It aims to make it easier for your users to learn how to use your program.  If configured by the program, Active Help is printed when the user triggers shell completion.
 
-For example, 
+For example,
-```
+
-bash-5.1$ helm repo add [tab]

 You must choose a name for the repo you are adding.

-bash-5.1$ bin/helm package [tab][tab]
+$ bin/helm package [tab][tab]

 ```
 
 **Hint**: A good place to use Active Help messages is when the normal completion system does not provide any suggestions. In such cases, Active Help nicely supplements the normal shell completions to guide the user in knowing what is expected by the program.

 ## Supported shells
 
 Active Help is currently only supported for the following shells:
-- Bash (using [bash completion V2](shell_completions.md#bash-completion-v2) only). Note that bash 4.4 or higher is required for the prompt to appear when an Active Help message is printed.
+- Bash (using [bash completion V2](completions/_index.md#bash-completion-v2) only). Note that bash 4.4 or higher is required for the prompt to appear when an Active Help message is printed.

Using "0" can simplify your code in situations where you want to blindly disable Active Help without having to call `cobra.GetActiveHelpConfig(cmd)` explicitly.
