 can then be printed on a common inkjet printer, cut and glued together into a
 larger poster.
 
+Features
+========
+
+Plakativ allows one to create a poster using one of three different approaches:
+
+ - I want a poster of size X
+ - I want a poster X times the input page page area
+ - I have X pages of paper and want to print the biggest possible poster on them
+
+Plakativ works on Windows, Linux and MacOS. It offers a GUI based on tkinter, a
+command line interface and can be used as a Python module. Everything is inside
+a single file.

+multiplying the area of the input page or by maximizing the poster size, given
