# Contributing guidelines ## Requirements for development - Node.js 18/20 - npm 9/10 ## Initialize development environment Use [`nvm`](https://github.com/nvm-sh/nvm?tab=readme-ov-file#installing-and-updating) to prepare environment. There is a [`.nvmrc`](../.nvmrc), so you just need to run in the root directory: ```sh nvm install nvm use # Now using node v20.8.0 (npm v10.1.0) ``` > You can setup [shell integration for nvm](https://github.com/nvm-sh/nvm?tab=readme-ov-file#deeper-shell-integration) to do this automatically when moving to directory. Install dependencies, and start to make ``` npm install ```
