While you can customize your content calendar to fit your specific needs, content calendars normally include your scheduled content pieces, status updates, upcoming promotional activity, partnerships, and existing content updates.
As soon as you click the Use the template button, you'll be immediately taken to Softr studio and can start working on the template. If you don't have a Softr account, you'll be prompted to register first (a Free account will work just fine).
All the Softr templates are completely free of charge and can be used with any of the Softr subscription plans. However, Free and Starter plans have a limitation on the number of application users, so you might need to consider a higher subscription plan to work with bigger team or need to scale at a certain points.
