+# Fuzzer for extractors
+
+## Table of contents
+1. [libextractorfuzzerbase](#ExtractorFuzzerBase)
+2. [libmp4extractor](#mp4ExtractorFuzzer)
+
+# <a name="ExtractorFuzzerBase"></a> Fuzzer for libextractorfuzzerbase
+All the extractors have a common API - creating a data source, extraction
+of all the tracks, etc. These common APIs have been abstracted in a base class
+called `ExtractorFuzzerBase` to ensure code is reused between fuzzer plugins.
+
+Additionally, `ExtractorFuzzerBase` also has support for memory based buffer
+`BufferSource` since the fuzzing engine feeds data using memory buffers and
+usage of standard data source objects like FileSource, HTTPSource, etc. is
+not feasible.
+
+# <a name="mp4ExtractorFuzzer"></a> Fuzzer for libmp4extractor
+
+## Plugin Design Considerations
+The fuzzer plugin for MP4 extractor uses the `ExtractorFuzzerBase` class and
+implements only the `createExtractor` to create the MP4 extractor class.
+
+##### Maximize code coverage
+Dict file (dictionary file) is created for MP4 to ensure that the required MP4
+atoms are present in every input file that goes to the fuzzer.
+This ensures that larger code gets covered as a range of MP4 atoms will be
+present in the input data.
+
+
+## Build
+
+This describes steps to build mp4_extractor_fuzzer binary.
+
+### Android
+
+#### Steps to build
+Build the fuzzer
+```
+  $ mm -j$(nproc) mp4_extractor_fuzzer
+```
+
+#### Steps to run
+Create a directory CORPUS_DIR and copy some MP4 files to that folder
+Push this directory to device.
+
+To run on device
+```
+  $ adb sync data
+  $ adb shell /data/fuzz/arm64/mp4_extractor_fuzzer/mp4_extractor_fuzzer CORPUS_DIR
+```
