Review: Meta Elements

Remember?
This is a good head set-up for an HTML document.

HTML
<!DOCTYPE html>
<html lang="en-US">
  <head>
    <meta charset="UTF-8">
    <meta name="description" content="A short description...">
    <meta name="author" content="Your Name">
    <meta name="keywords" content="Some, keywords, here...">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>My Way-Cool Awesome Site</title>
  </head>

</html>
