- Implement native C extension using Ruby's internal C API
- Add extensive safety warnings at build, load, and runtime
- Require THAW_BUILD_NATIVE=true environment variable to compile
- Include comprehensive documentation about risks and platform issues
- Provide ThawNative module with version and safety information

⚠️ WARNING: This extension is extremely dangerous and will likely crash
modern Ruby versions. It's provided only for users who understand the
risks and have no other alternatives.

- Clarify that gem supports Ruby 2.7+ through multiple implementations
- Document three modes: safe (default), native C extension, Ruby fallback
- Switch from Code Climate to qlty badges and links
- Fix incorrect GitHub repository references (active_record-framing → thaw)
- Correct typos in installation section
- Add comprehensive warnings about dangers of all implementations
- Emphasize Object#dup as the strongly recommended alternative

 ### Compatibility
 
-To-date, `thaw` works in Ruby `2.0` through `2.6`<sup>1</sup>.
+The gem **supports Ruby 2.7+** with significant safety concerns:
 
-Check the [build status](https://travis-ci.org/TwilightCoders/thaw) for the most current compatibility.
+- **Native C extension**: The only available implementation, extremely dangerous
+- **Safe fallback**: If compilation fails, shows error message and guides users to Object#dup
 
-<sup>1</sup>There seems to be a segmentation fault in Ruby `2.7` that I haven't had time to investigate.
+**⚠️ IMPORTANT:** The native extension is **extremely dangerous** and may cause crashes, memory corruption, or undefined behavior.
+
+**Strong Recommendation:** Use [`Object#dup`](https://www.rubyguides.com/2018/11/dup-vs-clone/) instead of trying to unfreeze objects.
+
+### Native C Extension
+
+The gem uses a **native C extension** to implement object unfreezing:
+
+```bash
+gem install thaw
+```
+
+**⚠️ EXTREME WARNING:** The native extension:
+- Manipulates Ruby's internal object representation directly
+- **Will likely cause segmentation faults** on modern Ruby versions
+- May have platform-specific compilation issues
+- Goes against Ruby's fundamental design principles
+- Requires a C compiler and Ruby development headers
+
+### No Ruby Fallback
+
+The dangerous Ruby/Fiddle fallback implementation has been **removed for safety**. If the native extension isn't available, the gem will show clear error messages and guide users toward `Object#dup`.
+
+### Current Status
+
+The gem is maintained for:
+- Historical compatibility and documentation
+- Clear deprecation warnings to guide users toward better alternatives
+- Demonstration of the risks involved in low-level object manipulation
