It's easy

Copy to SD Card

Will partition for you

Give you the choice of OS

Includes recovery partition

Programming

Python as the educational languagePython 2.7.3

Any language can compile for ARMv6

The most interesting part is controlling GPIO

GPIO

Attention

GPIO IN/OUT is 3.3vDo not use voltage levels greater than 3.3V

Arduino is 5V

Do not connect power supply to any other pin

Be careful of static electricity
