 ## Usage example
+You can find examples of usage in the `examples/` directory.
 
-TODO
+To see how the parser can be used to payload AAC stream so that it can be put in the MP4 container, run:
+```
+elixir examples/add_and_put_in_mp4.exs
+```
+
+When the script terminates, you can play the result .mp4 file with the following command:
+```
+ffplay output.mp4
+```
