+Before compiling the Java binding you first need to have the C runtime
 compiled and installed. You also need to find where your jni.h header
 is installed. It is part of the Java JDK, but it might be placed
-in different places on different platforms. The path to the jni.h 
-header should be assigned to the JNI_PATH variable in the beginning
-of the Makefile that you will find in the root directory of 
-the binding. Once this is done type:
+in different places on different platforms.
+The Makefile in this directory will try to figure out the location of
+jni.h, but if it doesn't succeed you should add it manually to the
+JNI_INCLUDES variable in the beginning of the Makefile.
