 ## Building and installing self-signed PowerToys MSIX package
-* Make sure you've built correct `powertoys.sln` configuration
-* Add `PowerToysTestKey.pfx` to the [TRCA store](https://docs.microsoft.com/en-us/windows-hardware/drivers/install/trusted-root-certification-authorities-certificate-store)

-## Removing all current PowerToys installations
+For the first-time installation, you should generate a self-signed certificate and add it to the [TRCA store](https://docs.microsoft.com/en-us/windows-hardware/drivers/install/trusted-root-certification-authorities-certificate-store). That could be done by simply running ` 
+generate_self_sign_cert.ps1` from a powershell admin. After that:
+
+* Make sure you've built the `Release` configuration of `powertoys.sln`
+* Launch `msix_reinstall.ps1` from the devenv powershell
+
+`msix_reinstall.ps1` removes the current PowerToys installation, restarts explorer.exe (to update PowerRename shell extension), builds `PowerToys-x64.msix` package, signs it with a PowerToys_TemporaryKey.pfx, and finally installs it.
+## Removing all .msi/.msix PowerToys installations
