    |_Output\
    |_Source\
    | |_Public\
    | |_Private\
    | |_MyTestModule.psd1
    |_Tests\
    |_build.ps1

It will then make sure you have to follwoing modules installed:
- PowerSehllGet (For publishing modules)
- PlatyPS (For managing Help documentation)
- Pester (For Unit Testing)
- PSScriptAnalyzer (For Lint analyzing scripts)
- InvokeBuild (For building the module)

It will then download the build.ps1 script from the GitHub repository
https://raw.githubusercontent.com/ScriptingChris/New-ModuleProject/main/Source/build.ps1
