+#### 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.

+GitBook Open uses fontawesome. During development, your local environment will use the free version. However, only the pro version will be accepted by CI. If you see the following error:
+
+```
+The GitBook icon is missing. It indicates that the dependencies were installed without the correct font-awesome package. These changes have probably been persisted in the Bun lockfile. Read the README for more information.
+```
+
+It means that you've changed the GBO dependencies and bundled in the free version. Only GitBook staff can help with this - if you're not on the GitBook team, please ping us in the PR and we'll help get things moving.

+If you are GitBook staff, you'll need our NPM token in your local environment.

+
+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.

+# GitBook V2
+
+This package contains the code for an experiment new version of the GitBook renderer.
+
+The goals of this new version are:
+
+- Optimize rendering to leverage Next.js ISR and static rendering
+- Leverage Node.js runtime and bigger instances to render bigger content
+- Evaluate Vercel and Cloudflare deployment options
+
+## Deployment
+
+#### Vercel
+
+The new version is deployed automatically to Vercel using a Github Action on every push.
+
+#### Cloudflare with Opennext-js
+
+The new version is deployed automatically to Cloudflare using a Github Action on every push.
+
+## Potential issues
+
+- [ ] We can't use `dynamicIO` because our root layout needs to fetch the params (https://github.com/vercel/next.js/discussions/71927)
+- [ ] How to do `nonce` for static resources when we can't use `headers()` (dynamic API) (https://nextjs.org/docs/app/building-your-application/configuring/content-security-policy)
+
+## Structure
+
+#### Middleware:
+
+Goals:
+- Route between dynamic and static routes
+  - If a token is in the cookies => dynamic route
+  - If a token is in the url => dynamic route
+  - Else => static route
+- High performances:
+  - It should not rely on data fetching
+
+#### URLs to support:
+
+Content URLs:
+
+- `docs.company.com/page`
+  - Middleware: rewrite to `/static/url/docs.company.com/page`
+  - Page component renders the page
+- `docs.company2.com/section/page`
+  - Middleware: rewrite to `/static/url/docs.company2.com/section/page`
+  - Page component renders the page
+- `docs.company3.com/section/sitespace/page`
+  - Middleware: rewrite to `/static/url/docs.company3.com/section/sitespace/page`
+  - Page component renders the page
+
+Content URLs (adaptive content or visitor authentication):
+
+- `docs.company.com/page`
+  - Middleware:
+    - If a token is in the cookies or url => dynamic route
+    - Else => rewrite to `/dynamic/url/docs.company.com/page`
+  - Page component renders the page
+    - Read the token from the url query params or cookies
+
+
+PDF export URLs:
+
+- `docs.company.com/page/~gitbook/pdf`
+  - Middleware: rewrite to `/dynamic/pdf/docs.company.com/page`
+  - Page component renders the page
+
+Images resizing:
+
+- `docs.company.com/~gitbook/image`
+  - Middleware: rewrite to `/dynamic/image/docs.company.com`
+  - Route handlers process the request
+
+Preview URLs:
+
+- `open.gitbook.com/sites/site_abc/page` (or `open.gitbook.com/~site/site_abc/page` to stay compatible?)
+  - Middleware: no rewrite
+  - Page component renders the page (dynamic?)
+     - Read the token from the url query params
+     - Read customizations override from the url query params
+
+
+Space PDF URLs:
+
+- `open.gitbook.com/spaces/space_abc/pdf`
+  - Middleware: no rewrite
+  - Page component renders the page (dynamic?)
+     - Read the token from the url query params
+     - Read customizations override from the url query params
+
+Development:
+
+- `localhost:3000/sites/site_abc/page`
+
+#### Routes:
+
+- Content
+    - [ ] `/static/url/[[...url]]/page.tsx`
+    - [ ] `/dynamic/url/[[...url]]/page.tsx`
+- Images resizing
+    - [ ] `/dynamic/image/[hostname]/route.ts`
+- PDF export
+    - [ ] `/dynamic/pdf/[[...url]]/page.tsx`
+    - [ ] `/spaces/[space]/pdf/page.tsx`
