+# Codecov Integration Setup Guide
+
+## ✅ Prerequisites
+
+1. **Codecov Account**: https://codecov.io
+2. **GitHub Repository Access**: You need admin access to SoroLabs/SoroTask
+3. **GitHub Secrets Access**: https://github.com/SoroLabs/SoroTask/settings/secrets/actions
+
+## 🔑 Setup Steps
+
+### Step 1: Generate Codecov Token
+
+1. Visit https://codecov.io and sign in with GitHub
+2. Select the SoroLabs organization
+3. Navigate to **Settings** → **Account** → **Upload token**
+4. Copy the generated token (do NOT share this publicly)
+
+### Step 2: Add GitHub Secret
+
+1. Go to https://github.com/SoroLabs/SoroTask/settings/secrets/actions
+2. Click **New repository secret**
+3. Name: `CODECOV_TOKEN`
+4. Value: Paste the token from Step 1
+5. Click **Add secret**
+
+### Step 3: Verify Installation
+
+1. Create a test branch: `git checkout -b test/coverage-setup`
+2. Make a small change
+3. Push and open a pull request
+4. GitHub Actions will run automatically
+5. Check the PR for the coverage report comment
+
+## 📊 What Gets Measured
+
+### Rust Coverage (cargo-tarpaulin)
+- Line coverage of contract code
+- Branch coverage
+- Excludes fuzz targets automatically
+- Timeout: 600 seconds
+
+### Frontend Coverage (Jest)
+- Statements, Branches, Functions, Lines
+- Covers Next.js React components
+- Minimum thresholds: 70% for all metrics
+- Excludes node_modules and .next
+
+## 🎯 Coverage Thresholds
+
+All metrics must meet **70% minimum**:
+- ✅ Statements: 70%+
+- ✅ Branches: 70%+
+- ✅ Functions: 70%+
+- ✅ Lines: 70%+
+
+## 📈 Viewing Reports
+
+- **Codecov Dashboard**: https://codecov.io/gh/SoroLabs/SoroTask
+- **Per-PR**: Codecov comment appears automatically
+- **Badge**: Add to README.md:
+  ```markdown
+  [![codecov](https://codecov.io/gh/SoroLabs/SoroTask/branch/main/graph/badge.svg?token=YOUR_TOKEN)](https://codecov.io/gh/SoroLabs/SoroTask)
