+# ImageKit In 7 Steps #
+
+## Step 1 - pip install django-imagekit (or clone the source and put the imagekit module on your path) ##
+
+## Step 2 - Add ImageKit to your models ##
+
+    # myapp/models.py
+
+    from django.db import models
+    from imagekit.models import ImageModel
+
+    class Photo(ImageModel):
+        name = models.CharField(max_length=100)
+        original_image = models.ImageField(upload_to='photos')
+        num_views = models.PositiveIntegerField(editable=False, default=0)
+
+        class IKOptions:
+            # This inner class is where we define the ImageKit options for the model
+            spec_module = 'myapp.specs'
+            cache_dir = 'photos'
+            image_field = 'original_image'
+            save_count_as = 'num_views'
+
+See `ImageModel` and `Options` for more information.
+
+## Step 3 - Create your specifications  ##
+
+    # myapp/specs.py
+
+    from imagekit.specs import ImageSpec 
+    from imagekit import processors 
+
+    # first we define our thumbnail resize processor 
+    class ResizeThumb(processors.Resize): 
+        width = 100 
+        height = 75 
+        crop = True
+
+    # now we define a display size resize processor
+    class ResizeDisplay(processors.Resize):
+        width = 600 
+
+    # now let's create an adjustment processor to enhance the image at small sizes 
+    class EnchanceThumb(processors.Adjustment): 
+        contrast = 1.2 
+        sharpness = 1.1 
+
+    # now we can define our thumbnail spec 
+    class Thumbnail(ImageSpec): 
+        access_as = 'thumbnail_image' 
+        pre_cache = True 
+        processors = [ResizeThumb, EnchanceThumb] 
+
+    # and our display spec
+    class Display(ImageSpec):
+        increment_count = True
+        processors = [ResizeDisplay]
+
+## Step 4 - Flush the cache and pre-generate thumbnails (ImageKit has to be added to INSTALLED_APPS for management command to work) ##
+
+    python manage.py ikflush myapp
+
+## Step 5 - Use your new model in templates ##
+
+    <div class="original">
+    <img src="{{ photo.original_image.url }}" alt="{{ photo.name }}">
+    </div>
+
+    <div class="display">
+    <img src="{{ photo.display.url }}" alt="{{ photo.name }}">
+    </div>
+
+    <div class="thumbs">
+    {% for p in photos %}
+    <img src="{{ p.thumbnail_image.url }}" alt="{{ p.name }}">
+    {% endfor %}
+    </div>
+
+## Step 6 - Play with the API ##
+
+    >>> from myapp.models import Photo
+    >>> p = Photo.objects.all()[0]
+    <Photo: MyPhoto>
+    >>> p.display.url
+    u'/static/photos/myphoto_display.jpg'
+    >>> p.display.width
+    600
+    >>> p.display.height
+    420
+    >>> p.display.image
+    <JpegImagePlugin.JpegImageFile instance at 0xf18990>
+    >>> p.display.file
+    <File: /path/to/media/photos/myphoto_display.jpg>
+    >>> p.display.spec
+    <class 'myapp.specs.Display'>
+
+## Step 7 - Enjoy a nice beverage ##
+
+    from refrigerator import beer
+
+    beer.enjoy()
