+## Development
+
+#### Installation
+
+Clone the repository and use [Bun](https://bun.sh/) to install dependencies and run the local development server.
+
+```
+bun install
+```
+
+#### Configuration
+
+To develop and test a GitBook space locally, first create a [GitBook API token](https://app.gitbook.com/account/developer) and put it in a `.env.local` file:
+
+```
+GITBOOK_TOKEN=gb_api_abc
+```
+
+#### Start the local server
+
+Run the Next.js development server.
+
+```
+bun dev
+```
+
+Then open the space in your web browser: `http://localhost:3000/<space>/`.
+
+#### Other commands
+
+-   `bun format`: format the code
+-   `bun lint`: lint the code
