Welcome to TimeSpan
The plugin ships with default settings, but allows you to change everything from: the message shown for a post that will take less than one minute; the message shown for any post over 1 minute; and the words-per-minute used to calculate the reading time.
Setup
Once the plugin is activated, you have two options: you can include it in your theme files (handy for WordPress developers), or you can let us do all the heavy lifting with automagic setup.
Include TimeSpan in Your Theme Files
<ol>
<li>Head over to the TimeSpan menu under Settings</li>
<li>Fill out the options on that page</li>
<li>Place the ‘echo do_shortcode(‘[time-span]’)’ shortcode wherever you’d like the data to show up in your theme file (e.g. page-home.php).</li>
<li>Click the blue “Save Changes” button.</li>
</ol>
That’s it!
Automagic Setup
The Automagic Setup will automatically insert the calculated time to read at the top of each of your posts. Here’s how to do that:
<ol>
<li>Head over to the TimeSpan menu under Settings</li>
<li>Fill out the options on that page</li>
<li>Check the box at the bottom labeled “Automatically insert the time to read at the top of Posts”.</li>
<li>Click the blue “Save Changes” button.</li>
</ol>
That’s it!
