+<h2>Retriever Plugin Help</h2>
+<p>
+This plugin replaces the short excerpts you normally get in RSS feeds
+with the full content of the article from the source website.  You
+specify which part of the page you're interested in with a set of
+rules.  When each item arrives, the plugin downloads the full page
+from the website, extracts content using the rules, and replaces the
+original article.
+</p>
+<p>
+There's a few reasons you may want to do this.  The source website
+might be slow or overloaded.  The source website might be
+untrustworthy, in which case using Friendica to scrub the HTML is a
+good idea.  You might be on a LAN that blacklists certain websites.
+It also works neatly with the mailstream plugin, allowing you to read
+a news stream comfortably without needing continuous Internet
+connectivity.
+</p>
+<p>
+However, setting up retriever can be quite tricky since it depends on
+the internal design of the website.  That was designed to make life
+easy for the website's developers, not for you.  You'll need to have
+some familiarity with HTML, and be willing to adapt when the website
+suddenly changes everything without notice.
+</p>
+<h3>Configuring Retriever for a feed</h3>
+<p>
+To set up retriever for an RSS feed, go to the "Contacts" page and
+find your feed.  Then click on the drop-down menu on the contact.
+Select "Retriever" to get to the retriever configuration.
+</p>
+<p>
+The "Include" configuration section specifies parts of the page to
+include in the article.  Each row has three components:
+</p>
+<ul>
+<li>An HTML tag (e.g. "div", "span", "p")</li>
+<li>An attribute (usually "class" or "id")</li>
+<li>A value for the attribute</li>
+</ul>
+<p>
+A simple case is when the article is wrapped in a "div" element:
+</p>
+<pre>
+    ...
+    &lt;div class="ArticleWrapper"&gt;
+      &lt;h2&gt;Man Bites Dog&lt;/h2&gt;
+      &lt;img src="mbd.jpg"&gt;
+      &lt;p&gt;
+        Residents of the sleepy community of Nowheresville were
+        shocked yesterday by the sight of creepy local weirdo Jim
+        McOddman assaulting innocent local dog Snufflekins with his
+        false teeth.
+      &lt;/p&gt;
+      ...
+    &lt;/div&gt;
+    ...
+</pre>
+<p>
+You then specify the tag "div", attribute "class", and value
+"ArticleWrapper".  Everything else in the page, such as navigation
+panels and menus and footers and so on, will be discarded.  If there
+is more than one section of the page you want to include, specify each
+one on a separate row.  If the matching section contains some sections
+you want to remove, specify those in the "Exclude" section in the same
+way.
+</p>
+<p>
+Once you've got a configuration that you think will work, you can try
+it out on some existing articles.  Type a number into the
+"Retrospectively Apply" box and click "Submit".  After a while
+(exactly how long depends on your system's cron configuration) the new
+articles should be available.
+</p>
+<h3>Techniques</h3>
+<p>
+You can leave the attribute and value blank to include all the
+corresponding elements with the specified tag name.  You can also use
+a tag name of just an asterisk ("*"), which will match any element type with the
+specified attribute regardless of the tag.
+</p>
+<p>
+Note that the "class" attribute is a special case.  Many web page
+templates will put multiple different classes in the same element,
+separated by spaces.  If you specify an attribute of "class" it will
+match an element if any of its classes matches the specified value.
+For example:
+</p>
+<pre>
+    &lt;div class="article breaking-news"&gt;
+</pre>
+<p>
+In this case you can specify a value of "article", or "breaking-news".
+You can also specify "article breaking-news", but that won't match if
+the website suddenly changes to "breaking-news article", so that's not
+recommended.
+</p>
+<p>
+One useful trick you can try is using the website's "print" pages.
+Many news sites have print versions of all their articles.  These are
+usually drastically simplified compared to the live website page.
+Sometimes this is a good way to get the whole article when it's
+normally split across multiple pages.
+</p>
+<p>
+Hopefully the URL for the print page is a predictable variant of the
+normal article URL.  For example, an article URL like:
+</p>
+<pre>
+    http://www.newssite.com/article-8636.html
+</pre>
+<p>
+...might have a print version at:
+</p>
+<pre>
+    http://www.newssite.com/print/article-8636.html
+</pre>
+<p>
+To change the URL used to retrieve the page, use the "URL Pattern" and
+"URL Replace" fields.  The pattern is a regular expression matching
+part of the URL to replace.  In this case, you might use a pattern of
+"/article" and a replace string of "/print/article".  A common pattern
+is simply a dollar sign ("$"), used to add the replace string to the end of the URL.
+</p>
+<h3>Background Processing</h3>
+<p>
+Note that retrieving and processing the articles can take some time,
+so it's done in the background.  Incoming articles will be marked as
+invisible while they're in the process of being downloaded.  If a URL
+fails, the plugin will keep trying at progressively longer intervals
+for up to a month, in case the website is temporarily overloaded or
+the network is down.
+</p>
+{{if $allow_images}}
+<h3>Retrieving Images</h3>
+<p>
+Retriever can also optionally download images and store them in the
+local Friendica instance.  Just check the "Download Images" box.  You
+can also download images in every item from your network, whether it's
+an RSS feed or not.  Go to the "Settings" page and
+click <a href="$config">"Plugin settings"</a>.  Then check the "All
+Photos" box in the "Retriever Settings" section and click "Submit".
