This page provides one-stop information, from learning about and selecting a CC license, to becoming aware of all the places you can share your work so others can benefit from it. Although the assignment only requires that you license your final project, please consider sharing it on one or more of the platforms listed on this site. If you do, include this in your reflection--the last part of your project.
While your assignment asks that you apply a Creative Commons license to your project, you might want to explore the different between CC licensing and copyright. This webpage provides a good overview of copyright.
