[MORE NOTES TO COME]

Installation:

There are three ways how you can get access to the app.

The simplest way is to just download it via the Microsoft Store.

2. Sideload:

If you don't want to use the Microsoft Store for getting access to UWPX you can also sideload a pre build app.
For this head over to releases and download the latest UWPX-Installer.exe.
Once downloaded, run it and you are ready to go!

For this to work you first have to enable Sideload app in your Windows settings! Click here for more information about this.

  1. Install Visual Studio 2022
  2. Clone the repo with Visual Studio 2022
