- Install AFL and the requirements for LLVM mode (see docs)
- Compile the fuzzing target, e.g.

  AFL_HARDEN=1 afl-clang-fast main.c -o fuzz-target -O3

  (other options, like using ASan or MSan are possible as well)
- Add additional test cases to testcase_dir
- Run afl, easiest (but inefficient) way;

  afl-fuzz -i testcase_dir -o findings_dir ./fuzz-target
