+  # POWERLEVEL9K_GOOGLE_APP_CRED_CLASSES is an array with even number of elements. The first
+  # element in each pair defines a pattern against which the current kubernetes context gets
+  # matched. More specifically, it's P9K_CONTENT prior to the application of context expansion
+  # (see below) that gets matched. If you unset all POWERLEVEL9K_GOOGLE_APP_CRED_*CONTENT_EXPANSION
+  # parameters, you'll see this value in your prompt. The second element of each pair in
+  # POWERLEVEL9K_GOOGLE_APP_CRED_CLASSES defines the context class. Patterns are tried in order.
+  # The first match wins.
+  #
+  # For example, given these settings:
+  #
+  #   typeset -g POWERLEVEL9K_GOOGLE_APP_CRED_CLASSES=(
+  #     '*:*prod*:*'  PROD
+  #     '*:*test*:*'  TEST
+  #     '*'           DEFAULT)
+  #
+  # If your current Google application credentials is "service_account deathray-testing x@y.com",
+  # its class is TEST because it doesn't match the pattern '* *prod* *' but does match '* *test* *'.
+  #
+  # You can define different colors, icons and content expansions for different classes:
+  #
+  #   typeset -g POWERLEVEL9K_GOOGLE_APP_CRED_TEST_FOREGROUND=28
+  #   typeset -g POWERLEVEL9K_GOOGLE_APP_CRED_TEST_VISUAL_IDENTIFIER_EXPANSION='⭐'

+      # '*:*prod*:*'  PROD    # These values are examples that are unlikely
+      # '*:*test*:*'  TEST    # to match your needs. Customize them as needed.
