+Software can be compiled, linked and built on the Pi itself, probably the easiest and most compatible approach.
+Executable image files can then be run on any other supported model of the Pi (0, 2 or 3).
+The faster speed of the Raspberry Pi 3 compiles the code about 3x faster than a Pi2, and takes a few minutes.
+
+Command line can be accessed either directly on the Pi itself (plug in HDMI monitor and USB keyboard) or remotely using a terminal window (Mac Utilities Terminal or Windows PC using PuTTY). The remote computer can be connected over Wi-Fi or Wired Ethernet using SSH.
+
+From a remote computer (can be over Wi-Fi or wired Ethernet), login using SSH by opening a Terminal window in Mac or using PuTTY in Windows
+
+    ssh pi@192.168.1.76
+    _[password]_ raspberry
+
+Or directly on the machine, login with username pi password raspberry

+    sudo su -
+    cd /root/stratux
+    service stratux stop
+    make
+    make install
+    service stratux start
+
+Explanation
+"sudo" enables supervisor privileges
+stopping the stratux service releases the executable files in use and also frees up processing capacity
+"make" invokes the Unix make process with the configuration file Makefile in the stratux directory
+"make install" makes that target, creating a new image file
+starting the stratux service runs the program again
