+# serendipity_plugin_piwik
+
+## Description
+
+This is just a small sidebar-plugin which can connect to your Piwik-installation. If you want to
+use it, you have to set up an user who has at least read-access to piwik. Within user-managment of
+piwik you can create a new one, if you don't want to use admin.
+
+If you don't need one part of the statistics, just disable it.
+
+If you want to change the order of output, install the plugin twice, it's stackable :)
+Now, you can can enable or disable any part of every instance until you are happy ;)
+
+## known bugs
+
+In some cases (i think, it only happens if main/index-page is in the top xx-list) page-url and page-title of section "most read entries" are not for the same page. I don't know why, but Piwik gives different output for the fetching of url and title and at the moment i don't know how i could solve this problem.
