+
+## 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
+```
