You have likely just received a request to schedule a "Pairing Session" or a technical interview with an engineer from Acklen Avenue or Hero Unit. These instructions are meant to help you set up your environment and get you ready for success in this next step in the vetting process. AFTER you finish setting up your environment, you'll be ready to schedule the interview (see link below).
A pair session is a collaborative, live coding session where two or more engineers will take turns writing code. We use various tools and techniques to make distributed coding and collaboration possible including screen sharing and an online IDE tuned for collaboration.
