+## Tests
+
+Because of a simple php file enabling persistent connection, you can not test the writables examples by only opening them in your browser.
+A url like file:///path/to/folder/test-writable-\*.html will not work.
+You need to run a localhost server that executes php and go to a url like http://localhost/renkan/test/test-writable-\*.html.
+
+For read only examples, it appears that for security reasons urls like file:///path/to/folder/test-readonly-\*.html only work on Firefox.
+To see those examples with other browsers, you also need to run a localhost server and go to a url like http://localhost/renkan/test/test-readonly-\*.html.
