Getting help

Gaining confidence using the built-in help system is an important part of working with PowerShell. In PowerShell, help is extensive; authors can easily write their own help content when working with functions, scripts, and script modules.

A number of commands are available to interact with the help system, as follows:

• Get-Help
• Save-Help
• Update-Help

Before exploring these commands, the concept of Updatable help should be discussed, as help may not be present on a system after installation.

Updatable help

Updatable help was introduced with PowerShell 3. It gives authors the option to store the most recent versions of their help documentation outside of PowerShell on web servers.
