-## Usage
-
-matplotview provides two methods, `view`, and `inset_zoom_axes`. The `view`
-method accepts two `Axes`, and makes the first axes a view of the second. The
-`inset_zoom_axes` method provides the same functionality as `Axes.inset_axes`,
-but the returned inset axes is configured to be a view of the parent axes.
-
 ## Examples
 
-An example of two axes showing the same plot.
-```python
-from matplotview import view
-import matplotlib.pyplot as plt
-import numpy as np
-
-fig, (ax1, ax2) = plt.subplots(1, 2)
-
-# Plot a line, circle patch, some text, and an image...
-ax1.plot([i for i in range(10)], "r")
-ax1.add_patch(plt.Circle((3, 3), 1, ec="black", fc="blue"))
-ax1.text(10, 10, "Hello World!", size=20)
-ax1.imshow(np.random.rand(30, 30), origin="lower", cmap="Blues", alpha=0.5,
-           interpolation="nearest")
-
-# Turn axes 2 into a view of axes 1.
-view(ax2, ax1)
-# Modify the second axes data limits to match the first axes...
-ax2.set_aspect(ax1.get_aspect())
-ax2.set_xlim(ax1.get_xlim())
-ax2.set_ylim(ax1.get_ylim())
-
-fig.tight_layout()
-fig.show()
-```

-An inset axes example.
-```python
-from matplotlib import cbook
-import matplotlib.pyplot as plt
-import numpy as np
-from matplotview import inset_zoom_axes
-
-def get_demo_image():
-    z = cbook.get_sample_data("axes_grid/bivariate_normal.npy", np_load=True)
-    # z is a numpy array of 15x15
-    return z, (-3, 4, -4, 3)
-
-fig, ax = plt.subplots(figsize=[5, 4])
+Examples can be found in the example gallery:
 
-# Make the data...
-Z, extent = get_demo_image()
-Z2 = np.zeros((150, 150))
-ny, nx = Z.shape
-Z2[30:30+ny, 30:30+nx] = Z
+[https://matplotview.readthedocs.io/en/latest/examples/index.html](https://matplotview.readthedocs.io/en/latest/examples/index.html)
 
-ax.imshow(Z2, extent=extent, interpolation='nearest', origin="lower")
+## Documentation
 
-# Creates an inset axes with automatic view of the parent axes...
-axins = inset_zoom_axes(ax, [0.5, 0.5, 0.47, 0.47])
-# Set limits to sub region of the original image
-x1, x2, y1, y2 = -1.5, -0.9, -2.5, -1.9
-axins.set_xlim(x1, x2)
-axins.set_ylim(y1, y2)
-axins.set_xticklabels([])
-axins.set_yticklabels([])
+Additional documentation can be found at the link below:
 
-ax.indicate_inset_zoom(axins, edgecolor="black")

-fractals also.
