+# DEVEDE NG #
+
+## WHAT IS IT? ##
+
+Devede NG is a rewrite of the Devede DVD disc authoring program. This new
+code has been writen from scratch, and uses Python 3 and Gtk3. It is also
+cleaner, which will allow to add new features in the future.
+
+
+## INSTALLING DEVEDE NG ##
+
+Just type:
+
+	sudo ./setup.py install
+
+
+## USING DEVEDE NG ##
+
+The first alpha version of Devede NG is very similar to the old devede, with the
+exception that, when creating a DVD disc, there are no more "titles" and
+"files". Instead, you just add files to the disc.
+
+The current visible changes are quite small in number:
+
+* Now allows to add several files at once
+* Now make better use of multicore systems by parallelizing the conversion of several movie files
+* The menu edition is interactive
+* Has a new "cut" resizing method, to allow to store as widescreen movies with black bars
+* Allows to create Matroska files with H.264 video and MP3 audio
+* Allows to use VLC or MPlayer for preview
+* Allows to choose between Brasero or K3B for burning the discs
+
+
+## THINGS TO DO ##
+
+Some of the future ideas to add to Devede NG are, without an specific order:
+
+* allow to set properties for several files in one step
+* add support for two-pass encoding
+* add more backends
+* add more output formats
+* allow to replace the movie's audio track with one or several MP3 or OGG audio files
+
+
+## History of versions ##
+* version 0.1 alpha 1 (2014-08-06)
