16. Algorithm: Get ready for work — Wake up — Shower — Put on clothes — Eat breakfast — Brush teeth — Catch the train — Get a coffee — Arrive at work
17. Oh, thats simple. Thats just my morning routine. I am a programmer! Not quite, but we're well on our way!
18. We need to create an algorithm that Alex can run. When Alex runs the steps Sam gives - we're executing a program! Now that's programming!
19. How do we speak with Alex? Alex understands and works with a specific set of instructions.
20. Programming <giving instructions>

39. Here's what you will be building — https://calm-cove-74202.herokuapp.com
40. Some pro-tips — Ask questions — Google — Take care for computer symbols: — Normally if it starts with a thing, it ends with the same thing, — ' is not the same as " ie. "Hello" 'Hello" — [], (), {}, etc. — Run rails server in one tab, run commands in another — Ask questions
41. Thanks Good luck Ask for help @gogogarrett
