The [ITK Python Quick Start Guide](https://itkpythonpackage.readthedocs.io/en/latest/Quick_start_guide.html) has been updated for ITK 5.0! 🎉

From basic examples, e.g.:

```python
import itk
import sys

input_filename = sys.argv[1]
output_filename = sys.argv[2]

image = itk.imread(input_filename)

median = itk.median_image_filter(image, radius=2)

itk.imwrite(median, output_filename)

```

to quick descriptions on how to:

- Mix ITK and NumPy
- Understand ITK Python types
- Instantiate an ITK object
- Specify filter parameters

this is a helpful resource when getting started in Python.

Enjoy ITK!
