		<h2 id="excerpt"><strong>Due to Twitter&#8217;s newest policies,</strong> every connection made to Twitter now has to be
			authenticated as coming from a source which is registered with Twitter. Because of this, to continue
			to use Tweet Nest, you have to <strong>register your Tweet Nest installation as an app with Twitter</strong>.</h2>
		<p class="intro">If you haven&#8217;t already done so, here&#8217;s a link to Twitter&#8217;s Developer Site where you can
			click the &#8220;Create new application&#8221; button to register (link opens in a new window):</p>
		<p><a class="proceed" href="http://dev.twitter.com/apps" target="_blank">Go to Twitter&#8217;s Developer Site</a></p>
		<p class="intro">When you do that, you get two strings in return, labeled the <em>consumer key</em> and the <em>consumer secret</em>.
			Paste them below:</p>

		<form action="" method="post">
		<div class="input">
			<label for="consumer_key">Twitter consumer key</label>
			<div class="field required"><input type="text" class="text code" name="consumer_key" id="consumer_key" value="<?php echo s($enteredConsumerKey); ?>" /></div>
			<div class="what">The consumer key of an app created and registered on <a href="http://dev.twitter.com/apps" target="_blank">dev.twitter.com</a>.</div>
		</div>
		<div class="input">
			<label for="consumer_secret">Twitter consumer secret</label>
			<div class="field required"><input type="text" class="text code" name="consumer_secret" id="consumer_secret" value="<?php echo s($enteredConsumerSecret); ?>" /></div>
			<div class="what">The consumer secret of the above.</div>
		</div>

		<h2><strong>That&#8217;s it!</strong></h2>

		<p class="intro">With the provided strings above, clicking the button below will now redirect your browser to Twitter to
			ask for your personal Twitter credentials, which will be used to let Tweet Nest access your tweets.</p>
