+Random Article Plugin For Pelican
 
+========================
 
+
 
+This plugin generates a html file which redirect to a random article
 
+using javascript's window.location. The generated html file is 
+saved at SITEURL.
 
+
 
+Only published articles are listed to redirect.
 
+
 
+
 
+Installation
 
+------------
 
+
 
+To enable, ensure that `random_article.py` is put somewhere that is accessible.
 
+Then use as follows by adding the following to your settings.py:
 
+
 
+    PLUGINS = ["random_article"]
 
+
 
+An easy way to find where pelican is installed is to verbose list the
 
+available themes by typing `pelican-themes -l -v`.
 
+
 
+Once the pelican folder is found, copy `random_article.py` to the `plugins` folder. Then
 
+add to settings.py like this:
 
+
 
+    PLUGINS = ["pelican.plugins.random_article"]
 
+
 
+Usage
 
+-----
 
+
 
+To use it you have to add in your config file the name of the file to use:
 
+
 
+    RANDOM = 'random.html'
 
+
 
+Then in some template you add:
 
+
 
+    <a href="{{ SITEURL }}/{{ RANDOM }}">random article</a>
