+## Key Features
+
+### Broken $ref Fallback
+When specs have broken `$ref` pointers, parser falls back to non-dereferenced mode:
+```typescript
+// In lib/parser.ts
+try {
+  spec = await SwaggerParser.dereference(specPath);  // Try first
+} catch {
+  spec = await SwaggerParser.parse(specPath);        // Fallback
+}
+```
+
+### .NET Name Sanitization
+Converts .NET-style schema names to valid TypeScript:
+```typescript
+// In tools/generate.ts - sanitizeName()
+"Namespace.Type"           → "Type"
+"Generic`1[Inner]"         → "Generic_Inner"
+"Company.Api.V5.ViewModel" → "ViewModel"
+```
+

+## Broken $ref Handling
+
+When a spec contains broken `$ref` pointers (e.g., typos in schema names), the parser:
+
+1. **Attempts** full dereferencing first
+2. **Falls back** to parsing without dereferencing if refs are broken
+3. **Warns** in output: "Spec has broken $refs. Parsed without dereferencing."
+
+This allows you to still extract metadata, query endpoints, and generate types from imperfect specs.
