  Building an app
 ================================================================================
 
-Instructions:
+For simple projects you can use the script located at build-scripts/androidbuild.sh
+
+There's two ways of using it:
+
+androidbuild.sh com.yourcompany.yourapp < sources.list
+androidbuild.sh com.yourcompany.yourapp source1.c source2.c ...sourceN.c
+
+sources.list should be a text file with a source file name in each line
+Filenames should be specified relative to the current directory, for example if
+you are in the build-scripts directory and want to create the testgles.c test, you'll
+run:
+    
+./androidbuild.sh org.libsdl.testgles ../test/testgles.c
+
+One limitation of this script is that all sources provided will be aggregated into
+a single directory, thus all your source files should have a unique name.
+
+Once the project is complete the script will tell you where the debug APK is located.
+If you want to create a signed release APK, you can use the project created by this
+utility to generate it.
+
+Finally, a word of caution: re running androidbuild.sh wipes any changes you may have
+done in the build directory for the app!
+
+
+For more complex projects, follow these instructions:
+    
 1. Copy the android-project directory wherever you want to keep your projects
    and rename it to the name of your project.
 2. Move or symlink this SDL directory into the <project>/jni directory
