+Slides Layout
+=============
+
+A slide is a hierarchy of three components :
+- The master slide upon which the slide is based : it specifies such properties as the font styles for the title, body, and footer, placeholder positions for text and objects, bullets styles, and background ;
+- The slide layout which is applied to the the slide : it permits to override what is specified in the master slide ;
+- The slide itself : it contains content and formatting that is not already specified by the master slide and the slide layout
+
+Placeholders permit to link these three components together in order that the override is possible.
+
+Master slides
+-------------
+
+You can access to all master slides with the method ``getAllMasterSlides`` or create on with ``createMasterSlide``.
