The New-MarkdownHelp cmdlet creates help in markdown format based on a module, a command, or a
file in Microsoft Assistance Markup Language (MAML) format.
The first command loads the PlatyPS module into the current session using the Import-Module
cmdlet.
The second command creates help for all the cmdlets in the PlatyPS module. It stores them in the
.\docs folder. This command specifies the Force parameter. Therefore, it overwrites existing
help markdown files that have the same name.
This command creates help in markdown format for the specified help MAML file. You don't have to
load the module, as in the previous example. If the module is already loaded, this command creates
help based on the MAML file, not on the currently installed module.
Example 4: Create help from an existing MAML file for use in a CAB file
This command creates help in markdown format for the specified help MAML file, as in the previous
example. This command also specifies the WithModulePage parameter and the ModuleName
parameter. The command creates a file named PSReadLine.md that contains links to the other markdown
files in this module and metadata that can be used to create .cab files.
Parameters
-AlphabeticParamsOrder
Order parameters alphabetically by name in PARAMETERS section. There are 5 exceptions: -Confirm,
