The Easy Mode, Windows-only way to run this repo is through BoxStarter. You can point boxstarter at the Install.ps1 file in this repo and it will install everything -- or you can point it at the "Install.ps1" file in any of the numbered folders to install that folder and everything lower that that.
In other words, if you use Edge to open https://boxstarter.org/package/url?https://github.com/Jaykul/BoxStarter-Boxes/raw/main/Install.ps1 it will install everything, just the way I like it.
If you don't want my customizations and extras, you could use https://boxstarter.org/package/url?https://github.com/Jaykul/BoxStarter-Boxes/raw/main/10_DevBox/Install.ps1.
The Hard Mode, Windows way to run this repo is to download it, unzip it, and run the Install.ps1 directly. That will install Chocolatey and BoxStarter and then run the rest of the Install.ps1 files in this repo.
