If you know your company already has a workshop set up, you can ask an admin to create an account for you by adding you to the workshop. Once you've been added, you will be able to see all your companies content.
If you just want to try out Showcase or create your own workshop, you will need to create an account from scratch.
To set up an account:
1: Visit https://app.showcaseworkshop.com/main/signup/
2: Fill out your details.
3: Confirm your info and you’re ready to go.
