[Your Own Module](https://www.ask-codey.com/lessons/powershell-modules) (Journeyman): A module is a folder of functions that PowerShell loads by name: the functions go in a .psm1 file, Export-ModuleMember chooses which ones others can call, New-ModuleManifest writes a .psd1 that gives the module a version and a description, and a folder on $env:PSModulePath lets PowerShell find it from anywhere.
