I've just published a comprehensive prompt engineering guide (170 pages) based on my GitHub repo with 3K+ stars. It covers 22 techniques with detailed explanations, exercises, and practical examples arranged in progressive difficulty. The guide teaches you to craft prompts that get faster, more accurate results from AI systems. Each chapter includes hands-on practice to ensure you've mastered the concepts. We sold 200 copies within the first two days of launch. Special launch discount (50% off) still available for the next 24 hours with code LAUNCHDAY.
