 To build a block editor, you need to install the following dependencies:
 
+ - `@wordpress/blocks`
  - `@wordpress/block-editor`
  - `@wordpress/block-library`
  - `@wordpress/components`
 
+## Appease package expectations
+
+The package `@wordpress/block-library` expects an env variable `IS_GUTENBERG_PLUGIN` to be defined. The quickest way to meet this requirement is to add it with `define` to the Vite config in `vite.config.js`. If using another bundler/build tool refer to its documentation for how to do this.
+
+```js
+import { defineConfig } from 'vite'
+import react from '@vitejs/plugin-react'
+
+// https://vitejs.dev/config/
+export default defineConfig({
+  // highlight-next-line
+  define: { 'process.env.IS_GUTENBERG_PLUGIN': false },
+  plugins: [react()],
+})
+```

 ## JSX
 
-We're going to be using JSX to write our UI and components. So one of the first steps we need to do is to configure our build tooling, By default vite supports JSX and and outputs the result as a React pragma. The Block editor uses React so there's no need to configure anything here but if you're using a different bundler/build tool, make sure the JSX transpilation is setup properly.

 That's it! You now have a very basic block editor with several block types included by default: paragraphs, headings, lists, quotes, images...
