+# Random TLS Extension Order Feature
+
+## Overview
+
+Random TLS extension order is **enabled by default** in httpx-tls. This feature randomizes the order of TLS extensions in the ClientHello message to help avoid fingerprinting and make connections less predictable while maintaining full protocol compatibility.
+
+## Why Randomize Extension Order?
+
+TLS fingerprinting tools and WAFs often use the specific order of TLS extensions as part of their fingerprinting process. By randomizing the extension order:
+
+- **Reduces fingerprinting**: Each connection can have a different extension order
+- **Maintains compatibility**: All required extensions are still sent, just in random order
+- **Bypasses detection**: Some security systems key on specific extension patterns
+
+## Usage
+
+### Default Behavior (Randomization Enabled)
+
+By default, all TLS profiles have randomization enabled:
+
+```python
+from httpx_tls import AsyncTLSClient
+from httpx_tls.profiles import TLSProfile
+
+# Randomization is enabled by default
+client = AsyncTLSClient(
+    tls_config=TLSProfile.create_from_version('chrome', 120)
+)
+
+# Or with JA3 string
+profile = TLSProfile.create_from_ja3(ja3)  # Randomization enabled by default
+
+# Or with user agent
+profile = TLSProfile.create_from_useragent(user_agent)  # Randomization enabled by default
+```
+
+### Disabling Randomization (for exact JA3 matching)
+
+If you need exact JA3 fingerprint matching, you can disable randomization:
+
+```python
+from httpx_tls.profiles import TLSProfile
+from httpx_tls import AsyncTLSClient
+
+# Disable in TLSProfile creation
+profile = TLSProfile.create_from_ja3(ja3, randomize_extensions=False)
+
+# Or when creating from version
+profile = TLSProfile.create_from_version('chrome', 120, randomize_extensions=False)
+
+# Or in AsyncTLSClient
+client = AsyncTLSClient(
+    tls_config=profile,
+    randomize_tls_extensions=False
+)
+```
+
+### Direct TLSProfile Instantiation
+
+```python
+from httpx_tls.profiles import TLSProfile
+
+# With randomization (default)
+profile = TLSProfile(
+    tls_version=(3, 4),
+    ciphers=[4865, 4866, 4867],
+    extensions=[51, 23, 13, 45, 65281, 5, 43],
+    groups=[29, 23, 24]
+    # randomize_extensions=True is the default
+)
+
+# Without randomization
+profile = TLSProfile(
+    tls_version=(3, 4),
+    ciphers=[4865, 4866, 4867],
+    extensions=[51, 23, 13, 45, 65281, 5, 43],
+    groups=[29, 23, 24],
+    randomize_extensions=False
+)
+```
+
+## Example Output
+
+**Without randomization:**
+```
+Extensions: [51, 23, 13, 45, 65281, 5, 43]
+```
+
+**With randomization (3 different runs):**
+```
+Run 1: [13, 23, 43, 65281, 51, 5, 45]
+Run 2: [43, 45, 5, 13, 23, 65281, 51]
+Run 3: [45, 23, 51, 13, 65281, 5, 43]
+```
+
+## Implementation Details
+
+### Changes Made
+
+1. **profiles.py**:
+   - Added `randomize_extensions` parameter to `TLSProfile.__init__()`
+   - Implemented `_randomize_extension_order()` method
+   - Updated `_set_order()` to apply randomization and enable `extension_order`
+   - Re-enabled the previously commented-out `settings.extension_order` assignment
+
+2. **client.py**:
+   - Added `randomize_tls_extensions` parameter to `AsyncTLSClient.__init__()`
+   - Automatically applies randomization flag to TLSProfile if provided
+
+### Technical Notes
+
+- Extension randomization uses Python's `random.shuffle()` for unpredictable ordering
+- All extensions from the original profile are preserved, only the order changes
+- The randomization happens at profile creation time
+- Each new TLSProfile instance with randomization enabled will have a different order
+
+## Security Considerations
+
+- **Compatibility**: Randomizing extension order is generally safe and maintains TLS protocol compatibility
+- **Fingerprint Variation**: Each connection will have a unique fingerprint when randomization is enabled
+- **Performance**: Minimal overhead - randomization happens once during profile creation
+
+## Testing
+
+Run the included test and example scripts:
+
+```bash
+# Run basic tests
+python test_randomization.py
+
+# Run usage examples
+python example_random_extensions.py
+```

 TLSProfile and Http2Profile classes and pass them to the async client during its creation. For example, to use httpx-tls with trio

+### Random TLS Extension Order
+
+By default, httpx-tls randomizes the order of TLS extensions to improve anti-detection. This feature is **enabled by default**.
+
+To **disable** randomization if you need exact JA3 fingerprint matching:
+
+```python
+from httpx_tls.profiles import TLSProfile
+from httpx_tls.client import AsyncTLSClient
+
+# Disable randomization in TLSProfile
+tls_config = TLSProfile.create_from_ja3(ja3, randomize_extensions=False)
+
+# Or disable in AsyncTLSClient
+client = AsyncTLSClient(
+    tls_config=tls_config,
+    randomize_tls_extensions=False  # Disable randomization
+)
+```
+
+**Note**: When randomization is enabled (default), each new connection will have a different extension order,
+making your fingerprint less predictable and harder to detect.

 ## Precautions (read this section before using httpx-tls)
 
 While I designed httpx-tls to not have obscure surprises in its API, there still are a few differences between httpx-tls 
 and httpx (mostly because of the underlying third-party dependencies) which are summarised below:

 httpx-tls does no certificate verification at all. Essentially, you can assume that the `verify` parameter when creating
