Calendar Rate installs automatically on to your Shopify store.
Once installed from the App store, you can enable and configure the app by going to Apps --> Calendar Rate --> Edit Settings, as described below.
Getting Started: Step-by-step
1. Go to the Apps section in your Shopify dashboard.
2. Go into the Calendar App.
3. Go to Edit Settings and enable and configure the settings of the App.
Once you've set your configurations, you can take a look at the app on your cart page above your 'Checkout' button. The first step is to fill out the shipping information form so that Calendar Rate can retrieve your shipping rules. This information will be passed on to the checkout process for review.
Calendar Rate is now ready to display your shipping rates in the calendar for selection by your customer.
