Prompt Engineering Guide

Open GitHub repoWhy it's picked
An encyclopedic guide to prompting: from basics through CoT, RAG and agent-related papers, with Chinese translations available. The one course to take if you want noticeably better output from AI.
Laojin's advice
Don't read it front to back — use it as a dictionary. Master the first few Techniques sections (zero-shot, few-shot, CoT) and you've covered 80% of daily needs; consult the rest on demand.
