+This plugin allows WordPress users to embed SlideOnline presentations into the blog posts. The code below is organized in the following way:
+First section contains procedures to embed the presentations using the shortcode [slideonline id=""]
+The second section contains directives to configure the oEmbed functionality into the WordPress by using a hook. This will allow to add
+SlideOnline as an oEmbed provider and then be able to use it by pasting the links.
