How to set terms and condition in the cart

I see that in cart.html there is code in erpnext/templates/pages/cart.html
which checks if terms should be shown.

           {% if doc.tc_name %}
                    <div class="cart-terms" style="display: none;" title={{doc.tc_name}}>
                    <div class="cart-link">
                            <a href="#" onclick="show_terms();return false;">*{{ __("Terms and Conditions") }}</a>
            {% endif %}

But in the shopping cart settings in the gui doctype I dont see any field to set terms and conditions to be shown in the cart.
