These articles are for later. You do not need any of them in your first hour. Each one covers one topic: what it is, when you need it, how it works in your app, what to ask Claude, and what to watch out for. Read one when the situation in the right-hand column comes up.

Article	Read it when
Checkpoints and undo	You are about to change something and want a way back, or a change went wrong
Many modules on one block	You want a second list like People or Tasks, such as Accounts or Hiring
Finding your way in the code	You want to know which file does what, so you can steer Claude
Changing a block	A change cannot be made in a module file and needs the screen itself to change
Skills	You keep asking Claude for the same job and want it done the same way each time
Taking a newer kit	A newer version of the kit is out and you want its fixes without losing your changes
Working with a mentor	You are stuck, or want a power user to check your work

How these differ from the course

The course is a path: lessons in order, each with steps and a "you are done when" check. These articles are not steps. They explain a topic so you can decide what to ask Claude. Most end with prompts to copy and a list of pitfalls.

If you have not finished lesson 7 yet, start with the course. If you are looking for a single job, such as adding a column, try Guides first.
