+## Building code
+
+### Build Prerequisites
+
+- Windows 10 1803 (build 10.0.17134.0) or above to build and run PowerToys.
+- Visual Studio 2019 Community edition or higher, with the 'Desktop Development with C++' component and the Windows 10 SDK version 10.0.18362.0 or higher.
+
+### Building the Code
+
+- Open `powertoys.sln` in Visual Studio, in the `Solutions Configuration` drop-down menu select `Release` or `Debug`, from the `Build` menu choose `Build Solution`.
+- The PowerToys binaries will be in your repo under `x64\Release`.
+- If you want to copy the `PowerToys.exe` binary to a different location, you'll also need to copy the `modules` and the `svgs` folders.
+
+### Building the .msi Installer
+
+* From the `installer` folder open `PowerToysSetup.sln` in Visual Studio, in the `Solutions Configuration` drop-down menu select `Release` or `Debug`, from the `Build` menu choose `Build Solution`.
+* The resulting `PowerToysSetup.msi` installer will be available in the `installer\PowerToysSetup\x64\Release\` folder.
+
+#### Prerequisites to Build the MSI Installer
+
+* Install the [WiX Toolset Visual Studio 2019 Extension](https://marketplace.visualstudio.com/items?itemName=RobMensching.WiXToolset).
+* Install the [WiX Toolset build tools](https://wixtoolset.org/releases/).
+
+### Building the MSIX Installer
+
+Please follow the [installer instructions](./installer/readme.md) which include items such as creating the self-signed cert for testing.
+
+## Debugging
+
+The following configuration issue only applies if the user is a member of the Administrators group.
+
+Some PowerToys modules require being run with the highest permission level if the current user is a member of the Administrators group. The highest permission level is required to be able to perform some actions when an elevated application (e.g. Task Manager) is in the foreground or is the target of an action. Without elevated privileges some PowerToys modules will still work but with some limitations:
+
+- the `FancyZones` module will be not be able to move an elevated window to a zone.
+- the `Shortcut Guide` module will not appear if the foreground window belongs to an elevated application.
+
+To run and debug PowerToys from Visual Studio when the user is a member of the Administrators group, Visual Studio has to be started with elevated privileges. If you want to avoid running Visual Studio with elevated privileges and don't mind the limitations described above, you can do the following: open the `runner` project properties and navigate to the `Linker -> Manifest File` settings, edit the `UAC Execution Level` property and change it from `highestAvailable (level='highestAvailable')` to `asInvoker (/level='asInvoker')`, save the changes.

 The PowerToys Runner contains the project for the PowerToys.exe executable.

 - Loading the individual PowerToys modules.
 - Passing registered events to the PowerToys.
 - Showing a system tray icon to manage the PowerToys.
