* A POSIX compliant operating system, MacOSX, [Android](https://github.com/google/honggfuzz/blob/master/docs/Android.md) or Windows (CygWin)
* GNU/Linux with modern kernel (>= v4.2) for hardware-based code coverage guided fuzzing (intel PT, Intel BTS, instruction/branch counting)
* An input corpus: You might be interested in the following for some common file formats:
- * Image formats: Tavis Ormandy's [Image Testuite](http://code.google.com/p/imagetestsuite/) has been effective at finding vulnerabilities in various graphics libraries.
+ * Image formats: Tavis Ormandy's [Image Testsuite](http://code.google.com/p/imagetestsuite/) has been effective at finding vulnerabilities in various graphics libraries.
* PDF: Adobe provides some [test PDF files](http://acroeng.adobe.com/).
* _**Note**: With the feedback-driven coverage-based modes, you can start your fuzzing without the input corpus._
