 Writing an image-based test is only slightly more difficult than a simple test.
 The main consideration is that you must specify the "baseline" or reference
 image, and compare it with a "generated" or test image. This is handled using
-the *decorator* functions `@check_figures_equal` and
-`@pytest.mark.mpl_image_compare` whose usage are further described below.

-#### Using check_figures_equal
-
-This approach draws the same figure using two different methods (the reference
-method and the tested method), and checks that both of them are the same.
-It takes two `pygmt.Figure` objects ('fig_ref' and 'fig_test'), generates a png
-image, and checks for the Root Mean Square (RMS) error between the two.
-Here's an example:
-
-```python
-@check_figures_equal()
-def test_my_plotting_case():
-  "Test that my plotting function works"
-  fig_ref, fig_test = Figure(), Figure()
-  fig_ref.grdimage("@earth_relief_01d_g", projection="W120/15c", cmap="geo")

 plug-in to test plot generating code.
 Every time the tests are run, `pytest-mpl` compares the generated plots with known
