1. Install Clang/LLVM and ensure it's in your PATH.
2. Create a fuzzing harness with `LLVMFuzzerTestOneInput`.
3. Compile the harness and target code with `-fsanitize=fuzzer,address`.
4. Create an initial corpus directory with seed inputs.
5. Run the fuzzer with `./fuzz corpus/`.
6. Monitor the output for crashes and coverage.
7. Minimize the corpus with `-merge=1`.
8. Re-run the fuzzer with the minimized corpus.
