+https://github.com/shaarli/Shaarli/issues/181 -  Add Disqus or Isso comments box on a permalink page  
+ * http://posativ.org/isso/
+ * install debian package https://packages.debian.org/sid/isso  
+ * configure server http://posativ.org/isso/docs/configuration/server/  
+ * configure client http://posativ.org/isso/docs/configuration/client/  
+ * http://posativ.org/isso/docs/quickstart/ and add `<script data-isso="//comments.example.tld/" src="//comments.example.tld/js/embed.min.js"></script>` to includes.html template; then add `<section id="isso-thread"></section>` in the linklist template where you want the comments (in the linklist_plugins loop for example)
+ 
+Problem: by default, Isso thread ID is guessed from the current url (only one thread per page).  
+if we want multiple threads on a single page (shaarli linklist), we must use : the `data-isso-id` client config,
+with data-isso-id being the permalink of an item.
+`<section data-isso-id="aH7klxW" id="isso-thread"></section>` 
+`data-isso-id: Set a custom thread id, defaults to current URI.`
+Problem: feature is currently broken https://github.com/posativ/isso/issues/27 
+Another option, only display isso threads when current URL is a permalink (`\?(A-Z|a-z|0-9|-){7}`) (only show thread
+when displaying only this link), and just display a "comments" button on each linklist item. Optionally show the comment
+count on each item using the API (http://posativ.org/isso/docs/extras/api/#get-comment-count). API requests can be done
+by raintpl `{function` or client-side with js. The former should be faster if isso and shaarli are on ther same server.
+Showing all full isso threads in the linklist would destroy layout

+### ► Play Videos plugin for Shaarli
+This plugin adds a `► Play Videos` button to [Shaarli](https://github.com/shaarli/Shaarli)'s toolbar. Click this button to play all videos on the page in an overlay HTML5 player. Nice for continuous stream of music, documentaries, talks...
+This uses code from https://zaius.github.io/youtube_playlist/ and is currently only compatible with Youtube videos.
+![](https://cdn.mediacru.sh/D_izf0zjAtxy.png)
+#### Installation and setup
+Place the files in the `tpl/plugins/playvideos/` directory of your Shaarli.
+This is a default Shaarli plugin, you just have to enable it.
+To enable the plugin, add `playvideos` to the `TOOLBAR_PLUGINS` config option in your `index.php` or `data/options.php`. Example:
+    $GLOBALS['config']['TOOLBAR_PLUGINS'] = array('aplugins', 'anotherone', 'playvideos');
+#### Troubleshooting
+If your server has [Content Security Policy](http://content-security-policy.com/) headers enabled, this may prevent the script from loading fully. You should relax the CSP in your server settings. Example CSP rule for apache2:
+`Header set Content-Security-Policy "script-src 'self' 'unsafe-inline' https://www.youtube.com https://s.ytimg.com 'unsafe-eval'"`

+## Save to Wallabag plugin for Shaarli
+For each link in your Shaarli, adds a button to save the target page in your [wallabag](https://www.wallabag.org/).
+### Installation/configuration
+Clone this repository inside your `tpl/plugins/` directory, or download the archive and unpack it there.  
+The directory structure should look like:
+```
+└── tpl
+    └── plugins
+        └── wallabag
+            ├── README.md
+            ├── wallabag.html
+            └── wallabag.png
+```
+To enable the plugin, add `'wallabag'` to your list of enabled plugins in `data/options.php` (`PLUGINS` array)
+. This should look like:
+```
+$GLOBALS['config']['PLUGINS'] = array('qrcode', 'any_other_plugin', 'wallabag')
+```
+Then, set the `WALLABAG_URL` variable in `data/options.php` pointing to your wallabag URL. Example:
+```
+$GLOBALS['config']['WALLABAG_URL'] = 'http://demo.wallabag.org' ; //Base URL of your wallabag installation
+```
