+
+LLVM LibFuzzer is an in-process, coverage-guided, evolutionary fuzzing engine. It feeds a series of
+fuzzed inputs via a "target" function and attempts to trigger crashes, memory bugs and undefined
+behavior. This article explains how to build and run existing fuzzers, implement new ones and
+visualize coverage provided by a fuzzer.
