-A simple plaintext presentation tool.
+sent is a simple plaintext presentation tool.
 
 sent does not need latex, libreoffice or any other fancy file format, it uses
-plaintext files and png images. Every line represents a slide in the
-presentation. This may limit the use, but for presentations using the [Takahashi
-method](https://en.wikipedia.org/wiki/Takahashi_method) this is very nice and
-allows you to write down the presentation for a quick lightning talk within a
-few minutes.
+plaintext files and png images. Every paragraph represents a slide in the
+presentation.

+The presentation is displayed in a simple X11 window. The content of each slide
+is automatically scaled to fit the window and centered so you also don't have to
+worry about alignment. Instead you can really concentrate on the content.
 
-The presentation is displayed in a simple X11 window colored black on white for
