 ### Getting Python and RepyV2
 
+**Note**: To make things more uniform for the programming labs, a Virtualbox image was created, with RepyV2 already built. Please check **EdStem**, where you will find details of the link to download the image, as well as an usage tutorial. **We stronly recommend using the Virtualbox image for these Programming Labs.** If you're using the Virtualbox image, you may skip the next Build Instructions step.
