+Compiling
+---------
+
+'./configure && make' should work for the most part.
+
+When compiling for ARM, it's advisable to tell configure script the CPU, FPU
+and ABI that matches your target system to get best performance, like this:
+
+CFLAGS='-mcpu=cortex-a8 -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp' ./configure
+
+Cross compilation should also work if kernel-style CROSS_COMPILE variable
+is set:
+CROSS_COMPILE='arm-none-linux-gnueabi-' ./configure
