# README Cleanup Summary

## Overview

Cleaned up outdated references in README.md and updated documentation to reflect the current state of the project.

## Issues Identified

### 1. Outdated Example References

**Problem**: README referenced several examples that no longer exist:
- `test_keys_yaml.rs` - Removed
- `debug_deepseek.rs` - Removed  
- `fetch_models_simple.rs` - Removed
- `longcat_dual.rs` - Removed

**Impact**: Users following the README would encounter errors when trying to run these examples.

### 2. YAML Configuration Confusion

**Problem**: README prominently featured `cargo run --example test_keys_yaml` as the primary troubleshooting tool, but:
- The example file doesn't exist
- YAML support is an optional feature (`yaml = ["config", "dep:serde_yaml"]`)
- No code in the repository uses `keys.yaml` for testing

**Impact**: Misleading users about available troubleshooting tools.

## Changes Made

### 1. Updated "Having Authentication Issues?" Section

**Before:**
```markdown
## 🚨 Having Authentication Issues?

**Test your API keys right now:**
```bash
cargo run --example test_keys_yaml
```

This will tell you exactly what's wrong with your API keys!
```

**After:**
```markdown
## 🚨 Having Authentication Issues?

See [Debugging & Troubleshooting](#debugging--troubleshooting) for detailed guidance on testing your API keys and resolving common issues.
```

### 2. Simplified Debugging & Troubleshooting Section

**Removed:**
- References to `test_keys_yaml`
- References to `debug_deepseek`
- Outdated troubleshooting guide references

**Added:**
- Practical troubleshooting steps for common issues
- Timeout error solutions
- Model not found solutions
- Direct actionable advice without relying on non-existent tools

### 3. Updated Examples Section

**Before:**
- Listed 6+ non-existent examples
- Included detailed descriptions of removed examples
- Misleading "⭐ New!" tags on old/removed features

**After:**
- Lists only actual existing examples (17 files)
- Organized by category:
  - Basic usage examples
  - Advanced examples (multi-modal, tools)
  - Utility examples
- Accurate descriptions matching actual file contents

## Related Changes

- Updated CHANGELOG.md to document these cleanup changes
- Added this summary document for future reference
- Maintained backward compatibility (no code changes)

## Recommendations

1. **Future**: Consider adding a CI check to verify example references in README
2. **Future**: Auto-generate examples list from `examples/` directory
3. **Future**: Add example descriptions as doc comments in example files themselves
