 ## Welcome
 
 Congratulations! After your hard work honing your Unix and Python skills, you've been selected for a bioinformatic research project! Soon, you're going to be trusted with genetic data from an unknown source. Your goal will be to use bioinformatics to determine where this data came from.

 This time, instead of having various files for various methods, we're going to be using just one file. Isn't that handy? Copy it to your directory:
 ```shell
-!wget --no-check-certificate 'https://docs.google.com/uc?export=download&id=1BNiRspwn7EiracdCLHy6mtwhnl3NTu-F' -O biopythonExercise.py
+!wget https://raw.githubusercontent.com/ubicucsd/crash_course/master/source/scripts/biopython.py -O biopythonExercise.py
 ```
 
 This program will provide you with feedback as you progress through the next few steps. Run the program as you complete each step. You'll find the [Biopython package documentation](http://biopython.org/DIST/docs/api/) useful.
