+#### 3. Install dependencies and run the project locally
+
+GitBook uses [Bun](https://bun.sh/) to run the project. Make sure you're using the specified version of `node` before running any of the development commands to ensure a smooth development experience.
+
+You can easily do this by running the command `nvm use`.

+To start your local version of GitBook, run the command `bun dev`.
+
+#### 4. Preview your changes
+
+When running the development server, published GitBook sites can be rendered through your local version at `http://localhost:3000/`.
+
+For example, our published docs can be viewed using the local version by visiting `http://localhost:3000/docs.gitbook.com` after running the development server.
+
+You can visit any published GitBook site behind your development server. Please make sure your site is [published publicly](https://docs.gitbook.com/published-documentation/publish-your-content-as-a-docs-site) to ensure you can view the site correctly in your development version.

+
+Cache backend, powered by Cloudflare Durable Objects. The cache is optimized for GitBook use-cases.
+
+### Performances
+
+The cache backend is optimized for performances by being distributed and accessible close to the worker locations that are reading it.
+
+### Geo-distribution
+
+To achieve a good balance between **performances** and **consistency**, cache objects are distributed over 7 locations, representing continents.
+
+It makes it possible to purge all 7 locations in one go and achieve fast consistency.
+
+### Concepts
+
+**Cache tag**: unique tag in the cache environment. A cache tag groups multiple keys that should be purged together in one operation.
+Cache tags should not contain a large set of unique keys. Exceeding thousands could lead to performances or reliability issues.
+
+**Cache key**: unique key in the cache environment. Each key should be assigned to a `tag`.
+
+**Location**: cache is distributed over 7 unique locations, one for each continent.
