+## Configuration
+The build of the documentation can be configured using environment variables. The following variables are available:
+- `SITE_ORIGIN`: The origin of the site, used for generating the sitemap. If not set, the sitemap will not be generated.
+- `BASE_PATH`: The base path of the site. All routes will be prefixed with this path.
