 Intel Arduino board
 -------------------
 The Edison used with the Arduino board has the following limitations
 in libmraa:
 
-- i2c is exposed on i2c-6, therfore you must use bus 6 and not bus 0
-- PWM avaible on default swizzler postions. (3,5,6,9)
+- I2C is exposed on i2c-6, therefore you must use bus 6 and not bus 0
+- PWM available on default swizzler positions. (3,5,6,9)
 - SPI exposed is also used for the ADC. Try not to use your own CS.
 - Max SPI speed is 25Mhz/4 ~6.25Mhz
 - SPI PM can sometimes do weird things you can disable it with:
-  echo on > /sys/devices/pci0000\:00/0000\:00\:07.1/power/control
+  `echo on > /sys/devices/pci0000\:00/0000\:00\:07.1/power/control`
 - ADC kernel module will return 12bit number but the ADC itself only has an
-  accuracy of 10bits. This ADC is only included on the arduino board.
-- AIO pins are treated as 0-5 in mraa_aio_init() but as 14-19 for everything
-  else. Therefore use mraa_gpio_init(14) to use A0 as a Gpio
-- Arduino pin 7 can sometimes negatively impact the wifi capability, if using
-  wifi avoid using this pin

+Because of the way IO is setup with the tristate on the Arduino breakout board
 IO will be flipped as it is setup. It's recommended to setup IO pins &
-direction before using them in a setup() method or similar. It's impossible on
+direction before using them in a `setup()` method or similar. It's impossible on
 this platform to avoid some GPIOs flipping on setup.
 
 Intel(R) breakout board
 -----------------------
 
-- Both I2C buses are avaible 1 & 6
+- Both I2C buses are available 1 & 6
 - IO on the miniboard is 1.8V
