+## 🌍 The Challenge
+
+**"Farm Navigators: Using NASA Data Exploration in Agriculture"**
+
+Smallholder farmers in Argentina and LATAM manage critical decisions — irrigation, crop rotation, nitrogen management — with little access to actionable Earth-science data. FarmHero bridges that gap with a playable simulation that puts NASA satellite insights into practice.
+
+---
+
+## 🎯 What FarmHero Does
+
+FarmHero is a **browser-based educational simulator** where players manage a 9-plot farm across multiple seasons. Every decision has real-world consequences based on NASA and CONAE Earth data:
+
+- 🌱 **Choose crops** across 9 plots — each with growth stages and phenological data
+- 💧 **Manage resources** — water, nutrients, soil health, soil capital, and money
+- 🔄 **Plan crop rotation** — to prevent soil degradation across seasons
+- 💡 **Learn irrigation methods** — from drip irrigation to flood, with water-efficiency tradeoffs
+- 🐄 **Handle livestock decisions** — understand nutrient cycles and environmental impact
+- 🌿 **Optimize nitrogen management** — balance yield and environmental footprint
+- 📍 **Select your region** — different climate zones affect every strategy
+- 📊 **Review season reports** — learn what worked and why
+
+---
+
+## 🛰️ NASA Data Integration
+
+FarmHero was built around the **NASA Space Apps challenge**, using Earth observation data to drive game mechanics:
+
+| Data Source | Used For |
+|---|---|
+| NASA Earth observation datasets | Crop growth models, regional climate parameters |
+| Phenological data | Seasonal crop stage progression |
+| CONAE (Argentine Space Agency) | Regional soil and precipitation context |

+## 🏆 Hackathon Story
+
+FarmHero was built in 48 hours at **NASA Space Apps Challenge 2025** in Rosario, Argentina.
+
+- 🥇 **Won the Rosario local event** — selected as the top project
+- 🌍 **Global Nominee** — advanced to the worldwide round
+- 🎯 **Challenge:** Farm Navigators — NASA Data Exploration in Agriculture
+- 📋 [See the full presentation](./Presentacion%20.pdf)
+
+The core insight: agricultural education doesn't require expensive tools. A well-designed browser simulation using real satellite data can teach sustainable farming decisions to anyone with a smartphone.
