 See the [`glob::Pattern` docs][glob::Pattern] for a more detailed
 specification of the glob matching syntax used for `--ignore`.
 
+On Windows, patterns should be specified with Windows-style (`\\`) separators.
+Unix-style separators (`/`) would not match Windows paths, which could be
+confusing and give the appearance of commandline ignores not working.
+
+From Cargo Watch 7.0.0, `/` in commandline ignores are automatically translated
+to `\\` when running on Windows, but one should still try to write the correct
+patterns for the platform, as there may be more subtle differences.
