 However, views with joined tables are not insertable ([see issue 907](https://github.com/mevdschee/php-crud-api/issues/907) ). As a workaround, use the property ***loginTable*** to set a different reference table for login. The **usersTable** will still be set to the normal, insertable users table. 
 
+#### Wordpress authentication
+
+The Wordpress authentication middleware defines three routes:
+
+    method path       - parameters                      - description
+    ---------------------------------------------------------------------------------------------------
+    GET    /me        -                                 - returns the user that is currently logged in
+    POST   /login     - username, password              - logs a user in by username and password
+    POST   /logout    -                                 - logs out the currently logged in user
+
+A user can be logged in by sending it's username and password to the login endpoint (in JSON format).
+The user can be logged out by sending a POST request with an empty body to the logout endpoint.
+In the authorization middleware you can use functions:
+
+- wp_get_current_user()
+- is_user_logged_in()
+- is_super_admin()
+- user_can(wp_get_current_user(),'edit_posts');
+
+Play with it and let me know how you like it.. :-)
