+Admin Site
+----------
+
+You can create and use a custom ``admin.AdminSite`` (see https://docs.djangoproject.com/en/4.2/ref/contrib/admin/).
+
+To do so, in your ``settings.py``, add:
+
+.. code-block:: python
+
+    from django.contrib import admin
+
+    class BrowserAdminSite(admin.AdminSite):
+        pass
+
+    DATA_BROWSER_ADMIN_SITE = BrowserAdminSite(name='data_browser')
+
+Then, in any ``admin.py``, register the models as usually but using ``DATA_BROWSER_ADMIN_SITE``.
+
+For instance in ``myapp/admin.py``:
+
+.. code-block:: python
+
+    from django.contrib import admin
+    from django.conf import settings
+    from myapp.models import MyAdminModel, MyBrowsableModel
+
+    # register in admin only
+    admin.register(MyAdminModel)
 
+    # register in data browser only
+    settings.DATA_BROWSER_ADMIN_SITE.register(MyBrowsableModel)
