+# Web Bluetooth Fuzzer
+
+The Web Bluetooth Fuzzer generates test pages that can be run as layout tests.
+These pages consist of a sequence of calls to the Web Bluetooth API whose
+purpose is to stress test the API's implementation and catch any bugs
+or regressions.
+
+This document describes the overall design of the fuzzer.
+
+[TOC]
+
+## Overview
+To generate test pages the fuzzer performs the following steps:
+
+1. Generate a test page that consists of a series of random calls to the API
+   with template parameters, calls to reload the page and calls to run garbage
+   collection.
+2. Replace the template parameters with random values.
+
+These generated test pages can then be run as Layout Tests in content_shell.
+
+## ClusterFuzz
+This fuzzer is designed to be run by ClusterFuzz and therefore takes three
+arguments, `--no_of_files`, `--input_dir`, and `--output_dir`.
+
+## Setup
+This fuzzer depends on files in:
+* `//src/third_party/WebKit/LayoutTests/resources`
+
+To ease development a setup.py script is included to copy over the necessary
+files to run the fuzzer locally. Additionally the script can be used to generate
+a .tar.bz2 file that can be uploaded to ClusterFuzz. To see the available
+options, run:
+```sh
+python setup.py -h
+```
