Editor

Development of the PowerShell syntax grammar is done using Visual Studio Code, so some of the workflow-elements are set up around that. That doesn't mean you can't use another editor, but you'll either need to run the build and test scripts manually, or set them up in the editor if it supports this.

NodeJS

The build script and the tests both require NodeJS installed. After cloning the repository, running npm install in the root directory should install all the needed packages, based on information in package.json.

PowerShell

While not strictly necessary for the development of the language grammars, some helper scripts are created as PowerShell scripts.
