 additional things to do.

+You have to set PROJECT_VERSION variable. This is important, because assets

 up to date. So that when you will install new STK version, this will force new 
 data extraction automatically.
 
-So that you have to:
-
-1. Change "data/supertuxkart.git" to "data/supertuxkart.VERSION_NUMBER"
-
-2. Open "src/utils/constants.cpp" and change:

-3. You can also update these lines in "android/AndroidManifest.xml":

+The PROJECT_CODE variable typically should be set to a value higher than for
+previous release, so that users will receive the upgrade.
