+# You can of course edit this file, but make sure you understand what you are

+# identify changes in the appearance of the library.

+# Before you change this file, please carefully consider whether such a change
+# is actually necessary. When you do change this file, it should almost always
+# be done in a dedicated commit directly on the `stable` branch and not part
+# of a release.  If you see this file being changed as part of a release,
+# block the release and work with the releaser to ensure that the change needs
+# to be propagated from the `develop` branch to the `stable` branch. In nearly
+# all cases, it should not be propagated from `develop` to `stable`.
+#
+# If you are a releaser and see this file change and you're not sure why, you
+# might have accidentally skipped [setting the correct
+# driver in your cloned
+# repository](https://github.com/material-components/material-components-ios/blob/develop/contributing/releasing.md#configure-the-merge-strategy-for-gitattributes).
+# If that's the case, please either revert the accidental change manually or
+# restart the release with a fresh clone and the correct driver.
