# Setting up the environment

This page describes what you need to install before you can run the tools from the various repositories. We expect that you use Windows 10 or Linux.

## Steps

1. On Windows 10, install the Windows Subsystem for Linux (WSL) with either the Ubuntu or Debian distribution.

2. Open a command line shell: Press `Win + R` and enter `bash`.

3. Install Node.js ([source](https://github.com/nodesource/distributions/blob/master/README.md#debinstall)):

    ```bash
    curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
    sudo apt-get install -y nodejs
    ```

4. Install npm modules:

    ```bash
    sudo npm install -g typescript
    ```
