+
+Oh, hello! Funny seeing you here.
+
+I appreciate your enthusiasm, but you aren't going to find much down here.
+There certainly aren't clues to any of the puzzles. The best surprises don't
+even appear in the source until you unlock them for real.
+
+Please be careful with automated requests; I'm not Google, and I can only take
+so much traffic. Please be considerate so that everyone gets to play.
+
+If you're curious about how Advent of Code works, it's running on some custom
+Perl code. Other than a few integrations (auth, analytics, ads, social media),
+I built the whole thing myself, including the design, animations, prose, and
+all of the puzzles.
+
+The puzzles probably took the longest; the easiest ones were around 45 minutes
+each, but the harder ones took 2-3 hours, and a few even longer than that. A
+lot of effort went into building this thing - I hope you're enjoying playing it
+as much as I enjoyed making it for you!
+
+If you'd like to hang out, I'm @ericwastl on Twitter.

+<article class="day-desc"><h2>--- Day 3: Squares With Three Sides ---</h2><p>Now that you can think clearly, you move deeper into the labyrinth of hallways and office furniture that makes up this part of Easter Bunny HQ. This must be a graphic design department; the walls are covered in specifications for triangles.</p>
+<p>Or are they?</p>
+<p>The design document gives the side lengths of each triangle it describes, but... <code>5 10 25</code>? Some of these aren't triangles. You can't help but mark the impossible ones.</p>
+<p>In a valid triangle, the sum of any two sides must be larger than the remaining side. For example, the "triangle" given above is <span title="Unless it's on a sphere!">impossible</span>, because <code>5 + 10</code> is not larger than <code>25</code>.</p>
+<p>In your puzzle input, <em>how many</em> of the listed triangles are <em>possible</em>?</p>
+</article>
+<p>Your puzzle answer was <code>917</code>.</p><article class="day-desc"><h2>--- Part Two ---</h2><p>Now that you've helpfully marked up their design documents, it occurs to you that triangles are specified in groups of three <em>vertically</em>. Each set of three numbers in a column specifies a triangle. Rows are unrelated.</p>
+<p>For example, given the following specification, numbers with the same hundreds digit would be part of the same triangle:</p>
+<pre><code>101 301 501
+102 302 502
+103 303 503
+201 401 601
+202 402 602
+203 403 603
+</code></pre>
+<p>In your puzzle input, and instead reading by columns, <em>how many</em> of the listed triangles are <em>possible</em>?</p>
+</article>
+<p>Your puzzle answer was <code>1649</code>.</p><p class="day-success">Both parts of this puzzle are complete! They provide two gold stars: **</p>
+<p>At this point, you should <a href="/2016">return to your advent calendar</a> and try another puzzle.</p>
