-## Source code formatting

-This repository uses the [fantomas][fantomas] and [prettier][prettier] tools to format the source code. There are no custom rules; we just use the default formatting. You can format the code by running the `./format.ps1` command.

-### Scripts
-
-The scripts in this repository are written in PowerShell. As PowerShell is cross-platform nowadays, you can also install it on [Linux](https://docs.microsoft.com/en-us/powershell/scripting/install/installing-powershell-core-on-linux?view=powershell-6) and [macOS](https://docs.microsoft.com/en-us/powershell/scripting/install/installing-powershell-core-on-macos?view=powershell-6).
