+## Fuzzing the Bitcoin Core P2P layer using Honggfuzz NetDriver
+
+Honggfuzz NetDriver allows for very easy fuzzing of TCP servers such as Bitcoin
+Core without having to write any custom fuzzing harness. The `bitcoind` server
+process is largely fuzzed without modification.
+
+This makes the fuzzing highly realistic: a bug reachable by the fuzzer is likely
+also remotely triggerable by an untrusted peer.
+
+To quickly get started fuzzing the P2P layer using Honggfuzz NetDriver:
+
+```sh
+$ mkdir bitcoin-honggfuzz-p2p/
+$ cd bitcoin-honggfuzz-p2p/
+$ git clone https://github.com/bitcoin/bitcoin
+$ cd bitcoin/
+$ ./autogen.sh
+$ git clone https://github.com/google/honggfuzz
+$ cd honggfuzz/
+$ make
+$ cd ..
+$ CC=$(pwd)/honggfuzz/hfuzz_cc/hfuzz-clang \
+      CXX=$(pwd)/honggfuzz/hfuzz_cc/hfuzz-clang++ \
+      ./configure --disable-wallet --with-gui=no \
+                  --with-sanitizers=address,undefined
+$ git apply << "EOF"
