@@ -6,11 +6,15 @@ Sigal is yet another simple static gallery generator. It's written in Python
 and it allows to build a static gallery of images with the following features:
 
 * process directories recursively,
-* resize images and create thumbnails,
 * generate HTML pages using jinja2 templates,
 * relative links for a portable output,
+* parallel processing,
 * MIT licensed.
 
+The idea behind Sigal is to ease the use of the javascript librairies like
+`galleria`_. These librairies do a great job to display the images, Sigal does
+what is missing: resize images, create thumbnails, generate html pages.
