+**Usage example**: _You have discovered a site that provides feeds which are hidden and inaccessible by normal means. You want your bridge to directly read the feeds and provide them via **RSS-Bridge**_
+
+Find a [template](#template) at the end of this file.
+
+**Notice:** For a standard feed only `collectData` need to be implemented. `collectData` should call `$this->collectExpandableDatas('your URI here');` to automatically load feed items and header data (will subsequently call `parseItem` for each item in the feed). You can limit the number of items to fetch by specifying an additional parameter for: `$this->collectExpandableDatas('your URI here', 10)` (limited to 10 items).
+
+## The `parseItem` method
+
+This method receives one item from the current feed and should return one **RSS-Bridge** item.
+The default function does all the work to get the item data from the feed, whether it is RSS 1.0,
+RSS 2.0 or Atom 1.0.
+
+**Notice:** The following code sample is just an example. Implementation depends on your requirements!
+
+```PHP
+protected function parseItem(array $item)
+{
+    $item['content'] = str_replace('rssbridge','RSS-Bridge',$item['content']);
+    return $item;
+}
+```
+
+### Feed parsing
+
+How rss-bridge processes xml feeds:
+
+Function | uri | title | timestamp | author | content
+---------|-----|-------|-----------|--------|--------
+`atom` | id | title | updated | author | content
+`rss 0.91` | link | title | | | description
+`rss 1.0` | link | title | dc:date | dc:creator | description
+`rss 2.0` | link, guid | title | pubDate, dc:date | author, dc:creator | description
+
+# Template
+
+This is the template for a new bridge:
+
+```PHP
+<?php
+class MySiteBridge extends FeedExpander
+{
+
+    const MAINTAINER = 'No maintainer';
+    const NAME = 'Unnamed bridge';
+    const URI = '';
+    const DESCRIPTION = 'No description provided';
+    const PARAMETERS = [];
+    const CACHE_TIMEOUT = 3600;
+
+    public function collectData()
+    {
+        $this->collectExpandableDatas('your feed URI');
+    }
+}
+```
