+# Windows Support
+
+short guide on using example build scripts on windows.
+
+## Requirements
+
+1. PowerShell (Version 5.0 and up preferred)
+2. git
+
+## Usage
+
+run setup script.
+
+```PowerShell
+./scripts/windows_setup.ps1 --setup
+```
+
+when running an example build script, the arguments and their order is
+important.
+
+```PowerShell
+./scripts/examples/gn_efr32_example.sh <AppRootFolder> <outputFolder> <efr32_board_name> [<Build options>]
+```
+
+for example:
+
+```PowerShell
+./scripts/examples/gn_efr32_example.ps1 /examples/lighting-app/efr32/ /out/lighting-app BRD4161A
+```
+
+To cleanup environment:
+
+```PowerShell
+./scrips/windows_setup.ps1 --cleanup
