#COFFEEANDPI

WELCOME TO COFFEE & PI!
• Who has worked with a Raspberry Pi before?
• Has anyone never touched or seen a Raspberry Pi?
• Windows or OS X?
• Is anyone from the suburbs or outside Center City?

RULES FOR THE WORKSHOP
• This is a beginner friendly workshop. All skill levels are
welcome. We were all beginners at one time.
• There are no stupid questions, only stupid people.
If you have a silly question, someone else might too. Ask anyway.
• I do not know everything. About anything.
If I don’t know, I will say so. When we learn something new, please
share it with anyone willing to listen.
• Even the greatest works of art started with someone learning the
basics and using their knowledge to practice their craft.
