--- title: Setting up the development environment order: 100 --- Open a terminal and enter the following command: ```bash npm init freesewing-pattern ``` This will load a few dependencies, and then ask you the following questions: - **Language**: Use the arrow keys to select the language of your choice - **Pattern name**: Enter `tutorial` - **description**: Enter `The FreeSewing tutorial` - **Pattern type**: Use the arrow key to select `Pattern` - **Department**: Use the arrow keys to select `Accessories` - **Author**: Enter your GitHub username - **GitHub repository**: This will be prefilled for you, so just hit Enter - **Package manager**: Use the arrow to choose. Pick `NPM` if you're not sure. After you've answered these questions, the default template will be copied, after which all dependencies will be installed. This will take a few minutes because we're loading some software for your development environment. When it's ready, you'll need to run two commands in parallel. In the current terminal, enter the directory that was just created for our `tutorial` pattern and start rollup in watch mode: ```bash cd tutorial npm run start ``` Or if you chose to use Yarn as package manager: ```bash cd tutorial yarn start ``` Now open a second terminal, and navigate to the `example` subfolder and run the same command there: ```bash: cd tutorial/example npm run start ``` Or if you chose to use Yarn as package manager: ```bash cd tutorial/example yarn start ``` If all goes well, your browser will open and show the following landing page: ![The FreeSewing development environment](./cfp.png) ###### Using Windows? We have tested this on Linux and MacOS, but not on Windows since I (joost) don't have a Windows machine I can test this on. If you run into any issues, join [our chatroom](https://discord.freesewing.org/) and we'll figure it out together.
