+# A python script to do both listening and talking. This is the basic model
+# for an audio-only mumble client.
+
+# Usage:
+
+# Install pyaudio (instructions: https://people.csail.mit.edu/hubert/pyaudio/#downloads)
+# If `fatal error: 'portaudio.h' file not found` is encountered while installing
+# pyaudio even after following the instruction, this solution might be of help:
+# https://stackoverflow.com/questions/33513522/when-installing-pyaudio-pip-cannot-find-portaudio-h-in-usr-local-include
+#
+# Install dependencies for pymumble.
+#
+# Set up a mumber server. For testing purpose, you can use https://guildbit.com/
+# to spin up a free server. Hard code the server details in this file.
+#
+# run `python3 ./listen_n_talk.py`. Now an audio-only mumble client is connected
+# to the server.
+#
+# To test its functionality, in a separate device, use some official mumble
+# client (https://www.mumble.com/mumble-download.php) to verbally communicate
+# with this audio-only client.
+#
+# Works on MacOS. Does NOT work on RPi 3B+ (I cannot figure out why. Help will
+# be much appreciated)
