+# 🎓 Welcome to Anthropic’s Prompt Engineering Interactive Tutorial
 
-## Course introduction and goals
+Hi there! 👋
+This hands-on course will teach you how to write better prompts for Claude, step by step. Whether you’re brand new to prompt engineering or just want to improve, you’re in the right place.
 
-This course is intended to provide you with a comprehensive step-by-step understanding of how to engineer optimal prompts within Claude.
+---
 
-**After completing this course, you will be able to**:
-- Master the basic structure of a good prompt 
-- Recognize common failure modes and learn the '80/20' techniques to address them
-- Understand Claude's strengths and weaknesses
-- Build strong prompts from scratch for common use cases
+## 🌟 What You’ll Learn
 
-## Course structure and content
+By the end of this course, you’ll know how to:
 
-This course is structured to allow you many chances to practice writing and troubleshooting prompts yourself. The course is broken up into **9 chapters with accompanying exercises**, as well as an appendix of even more advanced methods. It is intended for you to **work through the course in chapter order**. 
+* Understand what makes a prompt effective
+* Avoid common mistakes people make when prompting
+* Learn Claude’s strengths and limits
+* Create strong, reliable prompts for real-life situations
 
-**Each lesson has an "Example Playground" area** at the bottom where you are free to experiment with the examples in the lesson and see for yourself how changing prompts can change Claude's responses. There is also an [answer key](https://docs.google.com/spreadsheets/d/1jIxjzUWG-6xBVIa2ay6yDpLyeuOh_hR_ZB75a47KX_E/edit?usp=sharing).

-Note: This tutorial uses our smallest, fastest, and cheapest model, Claude 3 Haiku. Anthropic has [two other models](https://docs.anthropic.com/claude/docs/models-overview), Claude 3 Sonnet and Claude 3 Opus, which are more intelligent than Haiku, with Opus being the most intelligent.
+## 📚 How This Course Works
 
-*This tutorial also exists on [Google Sheets using Anthropic's Claude for Sheets extension](https://docs.google.com/spreadsheets/d/19jzLgRruG9kjUQNKtCg1ZjdD6l6weA6qRXG5zLIAhC8/edit?usp=sharing). We recommend using that version as it is more user friendly.*
+This course is made up of **9 short chapters** with exercises to help you practice what you learn. Each chapter builds on the previous one, so it’s best to go in order.
 
-When you are ready to begin, go to `01_Basic Prompt Structure` to proceed.
+You’ll find an **“Example Playground”** at the end of each chapter. That’s where you can test out the prompts and see how Claude responds when you change things.
 
-## Table of Contents
+👉 There’s also an [answer key here](https://docs.google.com/spreadsheets/d/1jIxjzUWG-6xBVIa2ay6yDpLyeuOh_hR_ZB75a47KX_E/edit?usp=sharing) to check your work.
 
-Each chapter consists of a lesson and a set of exercises.
+**Note:** This tutorial uses Claude 3 **Haiku**, which is fast and budget-friendly. There are also more powerful models like **Sonnet** and **Opus** — [learn more about them here](https://docs.anthropic.com/claude/docs/models-overview).
