+Part 1 Design B 
+===============
+
+This design allows you to turn four LEDs on and off with switches 0 and 1. Control LEDs 0 and 1 with switch 0 and LEDs
+2 and 3 with switch 1. To build this design run the following in the root symbiflow-example directory:
+
+.. code:: bash
+   :name: hello-arty-B
+
+   TARGET="arty_35" make -C projf-makefiles/hello/hello-arty/B"
+
+You can then download the bitstream by running:
+
+.. code:: bash
+
+   TARGET="arty_35" make download -C projf-makefiles/hello/hello-arty/B"

+Part 1 Design C
+===============
+
+This design has the same functionality in hardware as part C but demonstrates
+the use of conditional operators in System Verilog. To build this design run the
