+
+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.

-# Caching
-
-## Revalidating the cache
-
-Invalidate cache can be done at two levels using tags:
-
--   Data fetching cache
--   Rendering cache
-
-To invalidate and refetch the data cache, you can execute a POST request to `/~/gitbook/revalidate`:
-
-```bash
-curl --location --request POST 'https://gitbook/mycompany.com/~gitbook/revalidate' \
---header 'Content-Type: application/json' \
---data-raw '{"tags": ["space.id"]}'
-```
-
-To invalidate the rendering cache, the implementation mainly depends on the infrastructure serving the content, GitBook outputs a `Cache-Tag` header on every requests. The value of the header is a comma separated list of tags.
-
-## Purging the cache
-
-Purging the cache, without revalidating, is done by passing `"purge": true` in the request body.
