+## 🔥 Performance Comparison
+
+| Implementation | HTTP/2 Frame | HTTP/2 HPACK | Verdict |
+|----------------|--------------|--------------|---------|
+| **V (Ours)** | **0.34 μs** | **1.64 μs** | 🏆 **Winner** |

+
+## 🐛 Troubleshooting
+
+### "OpenSSL not found" (HTTP/3)
+```bash
+# macOS
+export LDFLAGS="-L/usr/local/opt/openssl@3/lib"
+export CPPFLAGS="-I/usr/local/opt/openssl@3/include"
+
+# Linux
+sudo ldconfig
+```
+
+### "ngtcp2 not found" (HTTP/3)
+```bash
+# Check installation
+pkg-config --modversion ngtcp2
+
+# Install from source if needed
+git clone https://github.com/ngtcp2/ngtcp2
+cd ngtcp2
+autoreconf -i && ./configure && make && sudo make install
+```
+
+### Can't install dependencies?
+**Use standalone tests:**
+```bash
+v run examples/http3/04_standalone_tests.v
+# Works without OpenSSL or ngtcp2
+```
