 This ensures that the plugin tolerates any kind of input (huge,
 malformed, etc) and thereby increasing the chance of identifying vulnerabilities.
 
+# <a name="amrWriterFuzzer"></a> Fuzzer for Amr Writer
+
+## Plugin Design Considerations
+The fuzzer plugin for AMR writer uses the `WriterFuzzerBase` class and
+implements only the `createWriter` to create the AMR writer class.
+
+##### Other considerations
+ * Two fuzzer binaries - amrnb_writer_fuzzer and amrwb_writer_fuzzer are generated based on the presence of a flag - 'AMRNB'

+#### Steps to build
+Build the fuzzer
+```
+  $ mm -j$(nproc) *_writer_fuzzer
+```
+
+#### Steps to run
+Create a directory CORPUS_DIR and copy some media files to that folder
+Push this directory to device.
+
+To run on device
+```
+  $ adb sync data
+  $ adb shell /data/fuzz/arm64/*_writer_fuzzer/*_writer_fuzzer CORPUS_DIR
