## Documentation Search Patterns

### Finding llms.txt

**ALWAYS try context7.com first:**

For GitHub repositories:
```
https://context7.com/{org}/{repo}/llms.txt
```

For websites:
```
https://context7.com/websites/{normalized-path}/llms.txt
```

With topic filter:
```
https://context7.com/{path}/llms.txt?topic={query}
```

**Fallback: Traditional search if context7.com returns 404:**
```
"[library] llms.txt site:[known-domain]"
```

**Alternative domains to try:**
```
site:docs.[library].com
site:[library].dev
site:[library].io
site:[library].org
```

### Finding Official Repository

**Search pattern:**
```
"[library] official github repository"
"[library] source code github"
```

**Verification checklist:**
- Check organization/user is official
- Verify star count (popular libraries have many)
- Check last commit date (active maintenance)
- Look for official links in README

### Finding Official Documentation

**Search patterns:**
```
"[library] official documentation"
"[library] docs site:official-domain"
"[library] API reference"
```

**Domain patterns:**
```
docs.[library].com
