+Install Segger J-Link Software
+------------------------------
+
+Some targets supported by Freedom E SDK (like the SiFive HiFive1 Rev B) use Segger J-Link OB
+for programming and debugging. If you intend to use these targets, install the Segger J-Link
+Software and Documentation Pack for your machine:
