 Make sure to change /nextcloud to the actual subfolder your Nextcloud instance is running in.
 
+.. note:: If you put the above directives directly into an Apache
+   configuration file (usually within ``/etc/apache2/``)
+   instead of ``.htaccess``, you need to prepend the first argument of
+   each ``RewriteRule`` option with a forward slash ``/``, for example
+   ``^/\.well-known/carddav``.
+   This is because Apache normalizes paths for the use in ``.htaccess``
+   files by dropping any number of leading slashes, but it does not
+   do so for the use in its main configuration files.

 If you are running NGINX, make sure ``location = /.well-known/carddav {`` and ``location = /.well-known/caldav {`` are properly configured as described in :doc:`../installation/nginx`, adapt to use a subfolder if necessary.
