@@ -11,11 +12,40 @@ Note: You probably don't need to use this gem, you probably want to [`.dup`](htt
### Compatibility
-To-date, `thaw` works in Ruby `2.0` through `2.6`1.
+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
-1There seems to be a segmentation fault in Ruby `2.7` that I haven't had time to investigate.
+**ā ļø 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
+```
+
+**ā ļø 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
