+PRU Software Support
+====================
+
+Two different packages are provided from the TI PRU software support
+code base.
+
+1. The include files and rpmsg static library for the PRU are
+   installed alongside the host package for the PRU code generation
+   tools package i.e. $(TI_CGT_PRU_INSTALLDIR).
+
+2. A target package for all the examples installed to
+   /usr/share/pru-software-support/. Users wanting to test a specific
+   example should copy or link it to a directory where the kernel
+   looks for firmware, e.g:
+
+ # cp /usr/share/pru-software-support/am335x/PRU_gpioToggle/gen/PRU_gpioToggle.out \
+   /lib/firmware/am335x-pru0-fw
+
+To get started with the PRU, have a look at the labs [1].
