 \\
+For this example I am going to use GPIO12 (or Physical Pin32).
 \\
+\\
+The steps to use the GPIO in PWM mode are very simple:
+\\
+\\
+  * Setup the Pin as an Output
+  * Setup the Pin in PWM Mode
+  * Start the PWM
+----
+==== Setup the GPIO Pin as an Output ====
+\\
+For this we need to just type in the following line:
+\\
+    gpio -g mode 12 out
+\\
+This sets the mode to Output
+\\
+----
+==== Set the GPIO Pin Mode to PWM ===
+\\
+    gpio -g mode 12 pwm
+\\
+This sets the GPIO Pin mode to PWM.
+\\
+----
+==== Set the PWM Frequency ====
+\\
+The PWM frequency is a 10 Bit number, so has a range of 0-1023
+\\
+    gpio -g pwm 12 50
+\\
+The Higher the number, the brighter the LED. Simple.
+\\
+\\
+----
+==== LED States ====
