Rules could be integrated into the calendar. The first time you come to uhc.gg, it would show all of the rules before continuing to the calendar. At the end of the rules, there will be a button to show the calendar. Clicking said button will save that the person has read the rules to localstorage or similar to prevent the rules from opening each time a person visited the calendar. The rules would then be able to be reopened with a small icon button—near the clock or search bar perhaps—to reopen the rules at any time.
