+    # We now use the ci-helpers package to set up our testing environment.
+    # This is done by using Miniconda and then using conda and pip to install
+    # dependencies. Which dependencies are installed using conda and pip is
+    # determined by the CONDA_DEPENDENCIES and PIP_DEPENDENCIES variables,
+    # which should be space-delimited lists of package names. See the README
+    # in https://github.com/astropy/ci-helpers for information about the full
+    # list of environment variables that can be used to customize your
+    # environment. In some cases, ci-helpers may not offer enough flexibility
+    # in how to install a package, in which case you can have additional
+    # commands in the install: section below.
+

+    # As described above, using ci-helpers, you should be able to set up an
+    # environment with dependencies installed using conda and pip, but in some
+    # cases this may not provide enough flexibility in how to install a
+    # specific dependency (and it will not be able to install non-Python
+    # dependencies). Therefore, you can also include commands below (as
+    # well as at the start of the install section or in the before_install
+    # section if they are needed before setting up conda) to install any
