What is CLAUDE.md?
CLAUDE.md is a project instruction file. Use it to tell Happycapy what to remember, how to work, and what rules to follow when it returns to the same Project.
You do not need to treat it like code. Think of it as the standing brief for a Project: the audience, tone, output rules, file locations, and review habits that should stay true across sessions.
Happycapy can create or update CLAUDE.md for you. You can also open Files, select the file, and edit it directly.
After you create a Project and start working, open Files to see the Project workspace. CLAUDE.md sits alongside uploaded source files and generated outputs, so future sessions can reuse the same instructions.
When to use it
Add something toCLAUDE.md when it should help future sessions in the same Project.
Good reasons include:
- You corrected Happycapy for the same thing more than once.
- The Project has rules you do not want to repeat every time.
- Future work needs the same audience, tone, file location, or review standard.
- Someone else opening the Project would need this context to get useful results.

Write instructions Happycapy can follow
CLAUDE.md guides Happycapy. It is not a hard safety switch, so clear and specific instructions work better than broad preferences.
A useful
CLAUDE.md is usually short, grouped with headings, and easy to scan.
Project and global instructions
Most Projects only need oneCLAUDE.md file in the Project workspace. Use broader locations only when the distinction matters.
If you are unsure where something belongs, start with the Project
CLAUDE.md. Keep the file focused on instructions that should apply to most future work in that Project.
