## tutorial

一个简单使用教程

```python
from csst_proto import flip_image
from astropy.io import fits

# read an L0 image
img = fits.getdata("CSST_MS_SCI_06_L0_img.fits")
# flip the image
img_flipped = flip_image(image=img)
```

## algorithm description

The `csst_proto` uses an awesome algorithm based on `numpy.ndarray` indices to flip images.
