+Compilation for Android
+-----------------------
+
+Super HUGS Revolution 98 depends on Python 2.7, Pygame 1.9.1, pgs4a 0.9.4.
+
+To compile Super HUGS Revolution for Android devices you need a
+working installation of Pygame Subset for Android (pgs4a) by
+Tom Rothamel and Patrick Dawson. pgs4a can be
+found at the following link:
+
+    http://pygame.renpy.org/
+
+Follow this steps to compile the game (instrucctions for GNU/Linux systems):
+
+    1) Move the Super-HUGS-Revolution-98 directory inside the pgs4a directory.
+    2) Cd to the pgs4a directory.
+    3) Execute "./android.py configure Super-HUGS-Revolution-98".
+    4) Answer the questions that will appear on the terminal.
+    5) Execute "./android.py build Super-HUGS-Revolution-98 release".
+
+This will produce a installable .apk file inside the bin directory of pgs4a.
+Compiling on Windows systems is similar.
+
