title: Add description feature to wordpress theme
body: <p>I have a section in my wordpress theme I started from scratch, in that section I have a title, tagline and a description.</p>
  
  <p>I am displaying them using:</p>
  
  <p>for title:</p>
  
  <pre><code>get_bloginfo();
  </code></pre>
  
  <p>for tagline:</p>
  
  <pre><code>get_bloginfo('description');
  </code></pre>
  
  <p>I need a way where the user can write a longer description of the site and display it.</p>
  
  <p>I only found on google how to add meta descriptions but that's not what I want.</p>
