### Adding Log Out
13+
14+
To log out of the application, we can add a button to the top of
15+
`app/views/layouts/application.html.erb`. This layout is where you put HTML that
16+
you want to include in every page like a header or footer.
17+
18+
Add a small `<nav>` section inside the `<body>` with a link to Home and a Log
19+
out button and wrap `yield` with a `<main>` tag.
20+
21+
```erb ins={5-8,10,12}
22+
<!DOCTYPE html>
23+
<html>
24+
<!-- ... -->
25+
<body>
26+
<nav>
27+
<%= link_to "Home", root_path %>
28+
<%= button_to "Log out", session_path, method: :delete if authenticated? %>
29+
</nav>
30+
31+
<main>
32+
<%= yield %>
33+
</main>
34+
</body>
35+
</html>
36+
```
37+
38+
This will display a Log out button only if the user is authenticated. When
39+
clicked, it will send a DELETE request to the session path which will log the
40+
user out.
