自定义主题的Wordpress插件开放时间

I am learning to build a custom Wordpress Theme from scratch. I would like to display opening times in the footer. I am trying to use this plugin but i can not find any documentation on it! I just want users to add their opening and close times using this and then output the opening/close times in the footer html. Does anyone have any experience using this plugin / know a better way i can achieve this?

HTML for foot.php

<div class="w-col w-col-6 w-col-stack">
      <h3 class="heading-6">OPENING TIMES</h3>
      <div class="open-times-wrapper">
        <ul class="unordered-list">
          <li class="open-li">MONDAY</li>
          <li class="closeinfo open-li">USER INPUT GOES HERE!</li>
        </ul>
        <ul class="unordered-list">
          <li class="open-li">TUESDAY</li>
          <li class="closeinfo open-li">10:30am - 00:00pm</li>
        </ul>
        <ul class="unordered-list">
          <li class="open-li">WEDNESDAY</li>
          <li class="closeinfo open-li">10:30am - 00:00pm</li>
        </ul>
        <ul class="unordered-list">
          <li class="open-li">THURSDAY</li>
          <li class="closeinfo open-li">10:30am - 00:00pm</li>
        </ul>
        <ul class="unordered-list">
          <li class="open-li">FRIDAY</li>
          <li class="closeinfo open-li">10:30am - 00:00pm</li>
        </ul>
        <ul class="unordered-list">
          <li class="open-li">SATURDAY</li>
          <li class="closeinfo open-li">10:30am - 00:00pm</li>
        </ul>
        <ul class="unordered-list">
          <li class="open-li">SUNDAY</li>
          <li class="closeinfo open-li">10:30am - 00:00pm</li>
        </ul>
      </div>
    </div>
