 A block development environment includes the tools you need on your computer to successfully develop for the Block Editor. The three essential requirements are:
 
 1.  [Code editor](#code-editor)
 2.  [Node.js development tools](#node-js-development-tools)
 3.  [Local WordPress environment (site)](#local-wordpress-environment)

 ## Code editor
 
-A code editor is used to write code, and you can use whichever editor you're most comfortable with. The key is having a way to open, edit, and save text files.

 If you do not already have a preferred code editor, [Visual Studio Code](https://code.visualstudio.com/) (VS Code) is a popular choice for JavaScript development among Core contributors. It works well across the three major platforms (Windows, Linux, and Mac), is open-source, and is actively maintained by Microsoft. VS Code also has a vibrant community providing plugins and extensions, including many for WordPress development.

 The list goes on. While modern JavaScript development can be challenging, WordPress provides several tools, like [`wp-scripts`](/docs/getting-started/devenv/get-started-with-wp-scripts.md) and [`create-block`](/docs/getting-started/devenv/get-started-with-create-block.md), that streamline the process and are made possible by Node.js development tools.
 
-**The recommended Node.js version for block development is [Active LTS](https://nodejs.org/en/about/previous-releases) (Long Term Support)**. However, there are times when you need to use different versions. A Node.js version manager tool like `nvm` is strongly recommended and allows you to easily change your `node` version when required. You will also need Node Package Manager (`npm`) and the Node Package eXecute (`npx`) to work with some WordPress packages. Both are installed automatically with Node.js.

-A local WordPress environment (site) provides a controlled, efficient, and secure space for development, allowing you to build and test your code before deploying it to a production site. The [same requirements](https://en-gb.wordpress.org/about/requirements/) for WordPress apply to local sites.
