Pluck is a very simple CMS, a content management system. Where you would usually have to edit the files of your website to change something and as such know some html code, a CMS alows you to make changes to your website on the website itself. You go to yourwebpage.com/administrator, you login and you have easy acces to the articles and menus of your site.
Pluck is able to satisfy you basic website needs by creating a one level menu with basic pages. It also manages picture albums, a simple blog and a contact form. Other alements can be added through modules, always with simplicity in mind.
We often install Pluck for customers that do not have any knowledge of managing webpages and do not have any time or interest of obtaining any.
Although no specific knowledge is required, you should take some time to get to know the program (asuming that your an unexperienced user) With the documentation that is available on the Pluck website learning should be quick and easy.
