BEST PRACTICES
2014
Comment your functions
• <#• .SYNOPSIS –a brief explanation of what the script or function does.• .DESCRIPTION – a more detailed explanation of what the script or
function does.• .PARAMETER name – an explanation of a specific parameter. Replace name with the parameter name. You can have one of these sections for each parameter the script or function uses.
• .EXAMPLE – an example of how to use the script or function. You can have multiple .EXAMPLE sections if you want to provide more than one example.
• .NOTES – any miscellaneous notes on using the script or function.• .LINK – a cross-reference to another help topic; you can have more
than one of these. If you include a URL beginning with http:// or https://, the shell will open that URL when the Help command’s –online parameter is used.
