 <p>Learn how you can use client-side Python on your webpage.
 Use the python <a href="https://docs.python.org/2/library/difflib.html"
  target="_blank">difflib</a> module to generate attractive online
 textual diffs.

 <p>The first run requires a large download. Please be patient.
 Also, as PNaCl translates executables to native code on demand,
 each program will also have have a noticable load delay on first run.
 We&#8217;re actively working to improve this.</p>

 Unfortunately, generating textual diffs is not one of them.
 Python on the other hand has the <a href="https://docs.python.org/2/library/difflib.html"
  target="_blank">difflib</a> module in its standard library.</p>
 <p>The starting point you&#8217;ve just extracted contains the shell
 of a web app using Portable Native Client Python to generate a diff.
 Just one thing is missing, that whole diffing thing...</p>
 <p>To see where things stand, deploy the sample like this:</p>
 <pre class="prettyprint">
 make
 </pre>
-<p>This will copy the sample to /tmp/differ (clobbering whatever is already
-there). It will also attempt to open the sample, but will be blocked by
-a popup blocker. Click on the URL to accept the popup.</p>
+<p>This will attempt to open the sample, but will be blocked by

+It also clobbers /tmp/differ for good measure.</p>
 <p>As you can see, this isn&#8217;t quite what we&#8217;re going for.</p>
 <p>You&#8217;ll want to modify diff.py, using the editor you selected earlier.
 You&#8217;ll probably want to consult the <a href="https://docs.python.org/2/library/difflib.html"
  target="_blank">difflib</a> documentation.
 I would suggest you check out the HtmlDiff class and make use of
-the make_file member function. I would also suggest the splitlines
+the make_file member function. Note our goal is to create a
+full HTML diff, so the make_table function is insufficient.
+I would also suggest the splitlines
 function may come in handy.</p>
 <p>You can test diff.py manually as you would in a normal UNIX environment.
 It can be run like this:</p>
 <pre class="prettyprint">
 ./diff.py before.txt after.txt out.html
 </pre>
 <p>Once everything is working diff.html will contain an html diff.
-Run <cite>make</cite> again to deploy and test the full app.</p>
+After the initial <cite>make</cite> you can hit &#8220;Run&#8221; to test your changes.</p>
 <p>Now get to it, and good luck!</p>
 <h2 id="what-you-ve-learned">What you&#8217;ve learned</h2>
 <p>While the details of building and packaging Python have been
 insulated from you for the purpose of this exercise, the key take-home lesson
 is how easy it is to leverage Python using PNaCl.
 As you&#8217;ve likely experienced, the initial start time is non-trivial.
 We&#8217;re working on improving this, both by improving PNaCl,
 and our Python port.</p>
 <p>The same approach to deploying Python apps can be used for the other
 interpreted languages that have been ported to PNaCl.</p>
