+# APyX - Simple Python-powered Antipixel geneation library
+
+This library provides facilities for generating programmatically
+Antipixels from Python.
+
+This is especially useful if you want to quickly generate batches
+of antipixels.
+
+
+## Usage example
+
+In its simplest form, you can call the ``create_antipixel()`` function, passing
+a configuration dictionary like this as the only argument:
+
+```python
+{
+    'base': {
+        'size': (80, 15),
+        'outline': '#000',
+        'background': '#fff',
+        'font_path': 'fonts/slkscr.ttf',
+    },
+    'parts': [
+        dict(text='DEBIAN', background='#d70751', color='#fff',
+             sizing='even', align='center'),
+        dict(text='LINUX', background='#fff', color='#d70751',
+             sizing='even', align='center'),
+    ],
+}
+```
+
+..but that's definitely tedious, so we'll automatize things a bit.
+
+```python
+here = os.path.dirname(__file__)
+output_dir = os.path.join(here, 'output')
+default_base = {
+    'size': (80, 15),
+    'outline': '#000',
+    'background': '#fff',
+    'font_path': os.path.join(here, 'fonts', 'slkscr.ttf'),
+}
+antipixels = {
+    'debian': {
+        'parts': [
+            dict(text='DEBIAN', background='#d70751', color='#fff',
+                 sizing='even', align='center'),
+            dict(text='LINUX', background='#fff', color='#d70751',
+                 sizing='even', align='center'),
+        ],
+    }
+}
+
+if __name__ == '__main__':
+    from apyx import create_antipixel
+
+    if not os.path.exists(output_dir):
+        os.makedirs(output_dir)
+
+    for name, config in antipixels.iteritems():
+        if 'base' not in config:
+            config['base'] = default_base
+        print("Creating antipixel {0}".format(name))
+        image = create_antipixel(config)
+        image.save(os.path.join(output_dir, '{0}.png'.format(name)))
+```
+
+Even better, we can use some "templates" for common patterns!
+So, that definition becomes:
+
+```python
+from apyx.templates import twoparts_even_altcolor
+
+antipixels = {
+    'debian': twoparts_even_altcolor('DEBIAN', 'LINUX', '#d70751', '#fff'),
+}
+```
+
+For a complete example, have a look at ``apyx_example.py``, in the main
+project folder.
