0.3 What you need on the table
You do not need a company laptop. You do not need a cloud bill for Volume 1.
- A notebook, paper or digital.
- A pen for boxes and arrows.
- This chapter list.
- Time to read one section and retell it aloud.
Later volumes may name scanners. This volume stays on paper. Do not hunt for install steps here. If a page names a tool, it names it so you recognise the word. It does not ask you to run it.
Accounts and secrets
- Do not paste passwords, card numbers, or Aadhaar numbers into notes you might share.
- If you draw a payment example, use fake amounts like 5000 and 1.
- Do not put real customer data in a practice file.
Ravindra Bagale's Tip
Students sometimes "make the lab realistic" by typing a real card number into a form. That is not realistic. That is a leak you caused. Fake numbers only.
