-* Add a numbered element for each pin enabled
+* Add a numbered element for each pin to enabled
 * `mode` - This controls whether the pin will be used for input or output. Accepted values are: `IN`, `OUT`. (Required)
 * `initial` - This controls the starting value of the pin. Accepted values are: `LOW`, `HIGH`. (Optional - defaults to `LOW`)
 * `resistor` - This controls the software defined pull up/pull down resistor available in the Broadcom SOC. Accepted values are: `PUD_UP`, `PUD_DOWN`. (Optional - defaults to none)
