 word_cloud
 ==========
 
-A fork of [Andreas Mueller](https://github.com/amueller)'s
-[word_cloud](https://github.com/amueller/word_cloud) to make it a little more
-extendable and installable as a package.
+A little word cloud generator in Python. Read more about it on the [blog
+post][blog-post].
 
-Install it by running:
-
-    pip install Cython
-    pip install numpy
-    pip install PIL
+## Installation
 
+Get this package:
+
     wget https://github.com/paul-nechifor/word_cloud/archive/master.zip
     unzip master.zip
+    rm master.zip
     cd word_cloud-master
-    sudo python setup.py install
-    cd ..
-    sudo rm -r word_cloud-master master.zip
 
-Run the files in `examples/` to for a short intro.
+Install it:
+
+    sudo pip install -r requirements.txt
+    sudo python setup
+
+## Examples
+
+Note that if you are not on Ubuntu, you need to adjust FONT_PATH to point to
+some existing font.
+
+Check out [examples/simple.py][simple] for a short intro. A sample output is:
+
+![Constitution](examples/constitution.png)
+
+Or run [examples/more.py][more] to see more options.
+
+## Used in
+
+### Reddit Cloud
+
+[Reddit Cloud][reddit-cloud] is a Reddit bot which generates word clouds for
+comments in submissions and user histories. You can see it being operated on
+[/u/WordCloudBot2][wc2] ([top posting][wc2top]).
+
+![A Reddit Cloud sample](http://i.imgur.com/tcbZnKW.png)

+### <other>
+
+*Send a pull request to add yours here.*
+
+## Issues
+
+Using Pillow instead of PIL might might get you the [`TypeError: 'int' object is
+not iterable` problem][intprob] also showcased on the blog.

     Notes
     -----
-    Larger Images with make the code significantly slower.
-    If you need a large image, you can try running the algorithm at a lower
-    resolution and then drawing the result at the desired resolution.
-
-    In the current form it actually just uses the rank of the counts,
-    i.e. the relative differences don't matter.
-    Play with setting the font_size in the main loop vor differnt styles.
-
-    Colors are used completely at random. Currently the colors are sampled
-    from HSV space with a fixed S and V.
-    Adjusting the percentages at the very end gives differnt color ranges.
-    Obviously you can also set all at random - haven't tried that.
