+# Use Docs as a Resource Server
+
+Docs implements resource server, so it means it can be used from an external app to perform some operation using the dedicated API.
+
+> **Note:** This feature might be subject to future evolutions. The API endpoints, configuration options, and behavior may change in future versions.
+
+## Prerequisites
+
+In order to activate the resource server on Docs you need to setup the following environment variables
+
+```python
+OIDC_RESOURCE_SERVER_ENABLED=True
+OIDC_OP_URL=
+OIDC_OP_INTROSPECTION_ENDPOINT=
+OIDC_RS_CLIENT_ID=
+OIDC_RS_CLIENT_SECRET=
+OIDC_RS_AUDIENCE_CLAIM=
+OIDC_RS_ALLOWED_AUDIENCES=
+```
+
+It implements the resource server using `django-lasuite`, see the [documentation](https://github.com/suitenumerique/django-lasuite/blob/main/documentation/how-to-use-oidc-resource-server-backend.md)
+
+## Customise allowed routes
+
+Configure the `EXTERNAL_API` setting to control which routes and actions are available in the external API. Set it via the `EXTERNAL_API` environment variable (as JSON) or in Django settings.
+
+Default configuration:
+
+```python
+EXTERNAL_API = {
+    "documents": {
+        "enabled": True,
+        "actions": ["list", "retrieve", "create", "children"],
+    },
+    "document_access": {
+        "enabled": False,
+        "actions": [],
+    },
+    "document_invitation": {
+        "enabled": False,
+        "actions": [],
+    },
+    "users": {
+        "enabled": True,
+        "actions": ["get_me"],
+    },
+}
+```
+
+**Endpoints:**
+
+- `documents`: Controls `/external_api/v1.0/documents/`. Available actions: `list`, `retrieve`, `create`, `update`, `destroy`, `trashbin`, `children`,  `restore`, `move`,`versions_list`, `versions_detail`, `favorite_detail`,`link_configuration`, `attachment_upload`, `media_auth`, `ai_transform`, `ai_translate`, `ai_proxy`. Always allowed actions: `favorite_list`, `duplicate`.
+- `document_access`: `/external_api/v1.0/documents/{id}/accesses/`. Available actions: `list`, `retrieve`, `create`, `update`, `partial_update`, `destroy`
+- `document_invitation`: Controls `/external_api/v1.0/documents/{id}/invitations/`. Available actions: `list`, `retrieve`, `create`, `partial_update`, `destroy`
+- `users`: Controls `/external_api/v1.0/documents/`. Available actions: `get_me`.
+
+Each endpoint has `enabled` (boolean) and `actions` (list of allowed actions). Only actions explicitly listed are accessible.
+
+## Request Docs
+
+In order to request Docs from an external resource provider, you need to implement the basic setup of `django-lasuite` [Using the OIDC Authentication Backend to request a resource server](https://github.com/suitenumerique/django-lasuite/blob/main/documentation/how-to-use-oidc-call-to-resource-server.md)
+
+Then you can requests some routes that are available at `/external_api/v1.0/*`, here are some examples of what you can do.
+
+### Create a document
+
+Here is an example of a view that creates a document from a markdown file at the root level in Docs.
+
+```python
+    @method_decorator(refresh_oidc_access_token)
+    def create_document_from_markdown(self, request):
+        """
+        Create a new document from a Markdown file at root level.
+        """
+
+        # Get the access token from the session
+        access_token = request.session.get('oidc_access_token')
+
+        # Create a new document from a file
+        file_content = b"# Test Document\n\nThis is a test."
+        file = BytesIO(file_content)
+        file.name = "readme.md"
+
+        response = requests.post(
+            f"{settings.DOCS_API}/documents/",
+            {
+                "file": file,
+            },
+            format="multipart",
+        )
+
+        response.raise_for_status()
+        data = response.json()
+        return {"id": data["id"]}
+```
+
+### Get user information
+
+The same way, you can use the /me endpoint to get user information.
+
+```python
+response = requests.get(
+    "{settings.DOCS_API}/users/me/",
+    headers={"Authorization": f"Bearer {access_token}", "Content-Type": "application/json"},
+)
+```

+## Feature flags
+
+The Find search integration is controlled by two feature flags:
+- `flag_find_hybrid_search`
+- `flag_find_full_text_search`
+
+If a user has both flags activated the most advanced search is used (hybrid > full text > title).
+A user with no flag will default to the basic title search.
+
+Feature flags can be activated through the admin interface.
