+# Use Chrome fingerprint (defaults to Chrome 142)

+### OS-Specific User Agents
+
+httpmorph supports different operating system user agents to simulate requests from various platforms:
+
+```python
+import httpmorph
+
+# macOS (default)
+session = httpmorph.Session(browser='chrome', os='macos')
+# User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) ...
+
+# Windows
+session = httpmorph.Session(browser='chrome', os='windows')
+# User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) ...
+
+# Linux
+session = httpmorph.Session(browser='chrome', os='linux')
+# User-Agent: Mozilla/5.0 (X11; Linux x86_64) ...
+```
+
+**Supported OS values:**
+- `macos` - macOS / Mac OS X (default)
+- `windows` - Windows 10/11
+- `linux` - Linux distributions
+
+The OS parameter only affects the User-Agent string, while all other fingerprinting characteristics (TLS, HTTP/2, JA3/JA4) remain consistent to match the specified browser profile.
+
+### Chrome 142 Fingerprint Matching
+
+httpmorph accurately mimics **Chrome 142** TLS fingerprints with:
+
+- **JA3N** ✅ Perfect match
+- **JA4** ✅ Perfect match
+- **JA4_R** ✅ Perfect match
+- **User-Agent**: `Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/142.0.0.0 Safari/537.36`
+- **TLS 1.3** with correct cipher suites and extensions
+- **HTTP/2** with Chrome-specific SETTINGS frame
+- **Post-quantum cryptography** (X25519MLKEM768)
+- **Certificate compression** (Brotli, Zlib)
+
+**Verify your fingerprint:**
+
+```python
+import httpmorph
+
+# Make a request to fingerprint checker
+response = httpmorph.get('https://suip.biz/?act=ja4', browser='chrome142')
+print(response.text)
+
+# You should see perfect matches for:
+# - JA4 fingerprint ✅
+# - JA3N fingerprint ✅
+# - User-Agent: Chrome/142.0.0.0 ✅
+```
+
+httpmorph achieves **perfect matches** for all modern fingerprints including JA3N, JA4, and JA4_R when tested against real Chrome 142 browsers.

 ## FAQ
 
 **Q: Why another HTTP client?**
 A: httpmorph combines the performance of native C with browser fingerprinting capabilities, making it ideal for applications that need both speed and realistic browser behavior.
 
+**Q: How accurate is the Chrome 142 fingerprint?**
+A: httpmorph achieves perfect matches for modern fingerprints including JA3N, JA4, and JA4_R. This is verified against real Chrome 142 browsers. Test your fingerprint at https://suip.biz/?act=ja4
+
 **Q: Is it production-ready?**
 A: No, httpmorph is still in active development and not yet recommended for production use.
 
 **Q: Can I use this as a drop-in replacement for requests?**
 A: For most common use cases, yes! We've implemented the most widely-used requests API. Some advanced features may have slight differences.
 
+**Q: Does it work with Cloudflare-protected sites?**
+A: Yes! httpmorph supports certificate compression (Brotli, Zlib) which is required for many Cloudflare-protected sites. We successfully tested with icanhazip.com and postman-echo.com.
+
 **Q: How do I report a bug?**
 A: Please open an issue on GitHub with a minimal reproduction example and your environment details (OS, Python version, httpmorph version).
