-
-## MSIX installer instructions
-
-### One-time tasks
-
-#### Create and install the self-sign certificate
-For the first-time installation, you'll need to generate a self-signed certificate.  The script below will generate and add a cert to your [TRCA store](https://docs.microsoft.com/en-us/windows-hardware/drivers/install/trusted-root-certification-authorities-certificate-store). 
-1. Open `Developer PowerShell for VS` as an Admin
-2. Navigate to your repo's `installer\MSIX`
-3. Run `.\generate_self_sign_cert.ps1`
-
-**Note:** if you delete the folder, you will have to regenerate the key
-
-#### Elevate `Developer PowerShell for VS` permissions due to unsigned file
-`reinstall_msix.ps1` is unsigned, you'll need to elevate your prompt.
-1. Open `Developer PowerShell for VS` as admin
-2. Run `Set-ExecutionPolicy -executionPolicy Unrestricted`
-
-#### Allow Sideloaded apps
-In order to install the MSIX package without using the Microsoft Store, sideloading apps needs to be enabled. This can be done by enabling `Developer Options > Sideload apps` or `Developer Options > Developer mode`. 
-
-### Building the MSIX package
-1. Make sure you've built the `Release` configuration of `powertoys.sln`
-2. Open `Developer PowerShell for VS`
-3. Navigate to your repo's `installer\MSIX`
-4. Run `.\reinstall_msix.ps1` from the devenv powershell
-
-### What reinstall_msix.ps1 does
-`reinstall_msix.ps1` removes the current PowerToys installation, restarts explorer.exe (to update PowerRename and ImageResizer shell extension), builds `PowerToys-x64.msix` package, signs it with a PowerToys_TemporaryKey.pfx, and finally installs it.
-
-## Cleanup - Removing all .msi/.msix PowerToys installations
-```ps
-$name='PowerToys'
-Get-AppxPackage -Name $name | select -ExpandProperty "PackageFullName" | Remove-AppxPackage
-gwmi win32_product -filter "Name = '$name'" -namespace root/cimv2 | foreach {
-  if ($_.uninstall().returnvalue -eq 0) { write-host "Successfully uninstalled $name " }
-  else { write-warning "Failed to uninstall $name." }
-}
-```
