The information under the section Purpose does not belong into this section. Please follow the guidelines (information between the <nowiki><!-- --></nowiki> tags) provided with the template.
As for the remaining sections, '''do not forget to add references''', especially to dates and hard data you mention! The media section is awfully short, please expand it with more information.
The reference number 3 is empty and needs fixing.
