-# poche
-Abandon Pocket, Instapaper and other Readability service : adopt poche. It is the same, but it is open source.
+# what is wallabag ?
+wallabag is a self hostable application allowing you to not miss any content anymore. Click, save, read it when you can. It extracts content so that you can read it when you have time.
 
-![poche](http://inthepoche.com/img/logo.png)
-
-The website of poche is [inthepoche.com](http://inthepoche.com).
-
-To get news from poche, [follow us on twitter](http://twitter.com/getpoche) or [read the poche blog](http://inthepoche.com/blog).
-
-[![flattr](http://api.flattr.com/button/flattr-badge-large.png)](http://flattr.com/thing/1265480/poche-a-read-it-later-open-source-system)
-
-## Usage
-You can easily add a "poched" page with the bookmarklet.
-
-poche save the entire content of a poched links : text and pictures are stored on your server.
-
-You can :
-* read a page in a comfortable reading view
-* archive a link
-* put a link in favorite
-* delete a link
-
-## Requirements & installation
-You have to install [sqlite for php](http://www.php.net/manual/en/book.sqlite.php) on your server.
-
-Get the [latest version](https://github.com/nicosomb/poche) of poche on github. Unzip it and upload it on your server. poche must have write access on assets, cache and db directories.
-
-That's all, **poche works** !
-
-## Security
-You **have** to protect your db/poche.sqlite file. Modify the virtual host of your website to add this condition :
-```apache
-<Files ~ "\.sqlite$">
-    Order allow,deny
-    Deny from all
-</Files>
-```
-
-Nginx version:
-```nginx
-location ~ /(db) {
-    deny all;
-    return 404;
-}
-```
-
-## Import from Pocket
-
-If you want to import your Pocket datas, [export them here](https://getpocket.com/export). Put the HTML file in your poche directory, execute import.php file locally by following instructions. Be careful, the script can take a very long time.

+// ------------------------------------
+// NOTE: You do not need an API key from fivefilters.org to run your own 
+// copy of the code. This is here if you'd like to restrict access to
+// _your_ copy.
+// Keys let you group users - those with a key and those without - and
+// restrict access to the service to those without a key.
+// If you want everyone to access the service in the same way, you can

+/// ADVANCED OPTIONS ////////////////////////////
+/////////////////////////////////////////////////
+
+// Enable XSS filter?
+// ----------------------
+// We have not enabled this by default because we assume the majority of
+// our users do not display the HTML retrieved by Full-Text RSS
+// in a web page without further processing. If you subscribe to our generated
+// feeds in your news reader application, it should, if it's good software, already
+// filter the resulting HTML for XSS attacks, making it redundant for
+// Full-Text RSS do the same. Similarly with frameworks/CMS which display
+// feed content - the content should be treated like any other user-submitted content.
+// 
+// If you are writing an application yourself which is processing feeds generated by
+// Full-Text RSS, you can either filter the HTML yourself to remove potential XSS attacks
+// or enable this option. This might be useful if you are processing our generated
+// feeds with JavaScript on the client side - although there's client side xss
+// filtering available too, e.g. https://code.google.com/p/google-caja/wiki/JsHtmlSanitizer
+// 
+// If enabled, we'll pass retrieved HTML content through htmLawed with
+// safe flag on and style attributes denied, see
+// http://www.bioinformatics.org/phplabware/internal_utilities/htmLawed/htmLawed_README.htm#s3.6
+// Note: if enabled this will also remove certain elements you may want to preserve, such as iframes.
+//
+// Valid values:
+// true - enabled, all content will be filtered
+// 'user' (default) - user must pass &xss in makefulltextfeed.php querystring to enable
+// false - disabled
+$options->xss_filter = 'user';
+
+// Allowed parsers
+// ----------------------
+// Full-Text RSS attempts to use PHP's libxml extension to process HTML.
+// While fast, on some sites it may not always produce good results. 
+// For these sites, you can specify an alternative HTML parser: 
+// parser: html5lib
+// The html5lib parser is bundled with Full-Text RSS.
+// see http://code.google.com/p/html5lib/
+//
+// To disable HTML parsing with html5lib, you can remove it from this list.
+// By default we allow both: libxml and html5lib.
+$options->allowed_parsers = array('libxml', 'html5lib');
+//$options->allowed_parsers = array('libxml'); //disable html5lib - forcing libxml in all cases
+
+// Enable Cross-Origin Resource Sharing (CORS)
+// ----------------------
+// If enabled we'll send the following HTTP header
+// Access-Control-Allow-Origin: *
+// see http://en.wikipedia.org/wiki/Cross-origin_resource_sharing
+$options->cors = false;
+
+// Use APC user cache?
+// ----------------------
+// If enabled we will store site config files (when requested 
+// for the first time) in APC's user cache. Keys prefixed with 'sc.'
+// This improves performance by reducing disk access.
+// Note: this has no effect if APC is unavailable on your server.
+$options->apc = true;
+
+// Smart cache (experimental)
+// ----------------------
+// With this option enabled we will not cache to disk immediately.
+// We will store the cache key in APC and if it's requested again
+// we will cache results to disk. Keys prefixed with 'cache.'
+// This improves performance by reducing disk access.
+// Note: this has no effect if APC is disabled or unavailable on your server,
+// or if you have caching disabled.
+$options->smart_cache = true;
+
+// Fingerprints
+// ----------------------
+// key is fingerprint (fragment to find in HTML)
+// value is host name to use for site config lookup if fingerprint matches
+$options->fingerprints = array(
+	// Posterous
+	'<meta name="generator" content="Posterous"' => array('hostname'=>'fingerprint.posterous.com', 'head'=>true),
+	// Blogger
+	'<meta content=\'blogger\' name=\'generator\'' => array('hostname'=>'fingerprint.blogspot.com', 'head'=>true),
+	'<meta name="generator" content="Blogger"' => array('hostname'=>'fingerprint.blogspot.com', 'head'=>true),
+	// WordPress (hosted)
+	// '<meta name="generator" content="WordPress.com"' => array('hostname'=>'fingerprint.wordpress.com', 'head'=>true),
+	// WordPress (self-hosted and hosted)
+	'<meta name="generator" content="WordPress' => array('hostname'=>'fingerprint.wordpress.com', 'head'=>true)
+);
+
+// User Agent strings - mapping domain names
+// ----------------------
+// e.g. $options->user_agents = array('example.org' => 'PHP/5.2');
+$options->user_agents = array( 'lifehacker.com' => 'PHP/5.2',
+							   'gawker.com' => 'PHP/5.2',

+							   '.wikipedia.org' => 'Mozilla/5.2',
+							   '.fok.nl' => 'Googlebot/2.1',
+							   'getpocket.com' => 'PHP/5.2'
+							  );
+
+// URL Rewriting
+// ----------------------
+// Currently allows simple string replace of URLs.
+// Useful for rewriting certain URLs to point to a single page
+// or HTML view. Although using the single_page_link site config
+// instruction is the preferred way to do this, sometimes, as
+// with Google Docs URLs, it's not possible.
+// Note: this might move to the site config file at some point.
+$options->rewrite_url = array(
+	// Rewrite public Google Docs URLs to point to HTML view:
+	// if a URL contains docs.google.com, replace /Doc? with /View?
+	'docs.google.com' => array('/Doc?' => '/View?'),

+	'.m.wikipedia.org' => array('.m.wikipedia.org' => '.wikipedia.org'),
+	'm.vanityfair.com' => array('m.vanityfair.com' => 'www.vanityfair.com')
+);
+
+// Content-Type exceptions
+// -----------------------
+// Here you can define different actions based
+// on the Content-Type header returned by server.
+// MIME type as key, action as value.
+// Valid actions:
+// * 'exclude' - exclude this item from the result
+// * 'link' - create HTML link to the item
+$options->content_type_exc = array(

+							   'audio' => array('action'=>'link', 'name'=>'Audio'),
+							   'video' => array('action'=>'link', 'name'=>'Video')
+							  );
+
+// Cache directory level
+// ----------------------
+// Spread cache files over different directories (only used if caching is enabled).
+// Used to prevent large number of files in one directory.
+// This corresponds to Zend_Cache's hashed_directory_level
+// see http://framework.zend.com/manual/en/zend.cache.backends.html
+// It's best not to change this if you're unsure.
+$options->cache_directory_level = 0;
+
+// Cache cleanup
+// -------------
+// 0 = script will not clean cache (rename cachecleanup.php and use it for scheduled (e.g. cron) cache cleanup)
+// 1 = clean cache everytime the script runs (not recommended)
+// 100 = clean cache roughly once every 100 script runs
+// x = clean cache roughly once every x script runs
