+=====================
 
 Galileo is a microcontroller board based on the Intel® Quark SoC X1000
 Application Processor, a 32-bit Intel Pentium-class system on a chip.
 
-The rev H board has the following limitations in libmraa:
+The Gen 2 board has the following limitations in libmraa:
 
 - i2c is set at 400Khz speed cannot be changed without reloading kernel module
 - i2c bus is shared with multiple devices, scanning it usually fails
 - pwm period is set globally for all pwm channels, when changed this will halt
   all pwm channels
+- adc kernel module will return 12bit number but the ADC itself only has an
+  accuracy of 10bits.
