1. Create a GitHub account
GitHub is a way for teams to collaborate on code together. It also comes in handy because it has version control; just in case you need to restore or reference a previous version of your code. The following article is also helpful in getting familiar with how it works: https://guides.github.com/activities/hello-world/. You can access GitHub via a browser, a terminal, or a desktop client If your team ends up using GitHub and you are not familiar with using a terminal, the desktop client is a great way to get started. Here is the link to do so: https://desktop.github.com/.

2. Bring a resume
It's a good idea to bring a couple copies of your resume if you are looking for a position. Sponsors are potentially looking for interns, co-ops, and even full-time employees. Even if you are not set on looking for a position, it might be a good idea to have a copy just in case you hear about something you are interested in. You can also always grab business cards to contact employers in the future!
