title: Where can I find documentation/tutorial(s) for Mutagen? (Python)

  <a href="https://stackoverflow.com/questions/6171565/how-do-i-read-album-artwork-using-python">How do I read album artwork using python?</a></p>
  
  <p>I got 'stuck' as it were. </p>
  
  <p>I have spent forever looking for documentation online but haven't come across any. I know that a lot of responses suggest reading the internal docstrings etc. but to be honest this is the first time I've come across a library without adequate documentation and its (to be honest) a little daunting. </p>
  
  <p>Does anyone have any ideas on how to approach the code? </p>
  
  <p>Thanks </p>
