+Troubleshooting
+---------------
+
+A ``NoBackendError`` exception means that the library could not find one of
+the libraries or tools it needs to decode audio. This could mean, for example,
+that you have a broken installation of `FFmpeg`_. To check, try typing
+``ffmpeg -version`` in your shell. If that gives you an error, try installing
+FFmpeg with your OS's package manager (e.g., apt or yum) or `using Conda
+<https://anaconda.org/conda-forge/ffmpeg>`_.
