Pull request overview
This PR improves Chapter 02’s documentation for Copilot CLI session management by clarifying how --resume/--continue behave in real workflows (session IDs, multiple terminals, and switching sessions mid-session), and removes redundant content in the optional section.
Changes:
- Adds an FAQ-style callout explaining how to discover session IDs via the interactive
copilot --resumepicker. - Documents multi-terminal behavior and introduces
/resumefor switching sessions without restarting. - Removes the duplicated “Switch Sessions While Working” subsection from the optional/deeper section.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.
| > **What about multiple terminals?** Each terminal window is its own session with its own context. If you have Copilot CLI open in three terminals, that's three separate sessions. Running `--resume` from any terminal lets you browse all of them. The `--continue` flag grabs whichever session was closed most recently, no matter which terminal it was in. | ||

The fenced code block inside this callout doesn’t specify a language (elsewhere in this README, blockquoted examples use bash for consistency and syntax highlighting). Consider changing this fence to bash to match the other CLI examples.
