This link provides step-by-step instructions to help you begin work on your ePortfolio. The ePortfolio allows you to collect artifacts which demonstrate what you've learned and reflect upon how you learn. You can showcase and share what you've learned using the presentation feature.
Features are available to help you gather artifacts and sort your artifacts. In addition, you can share artifacts or presentations and get feedback from others.
Take some time to review the documentation to help get you started.
