+# Notice: No need to configure anything in this section if your app uses only "en"
+# or if you use the i18n extra below
+#
+# Examples:
+# load the "de" built-in locale:
+# Pagy::I18n.load(locale: 'de')
+#
+# load the "de" locale defined in the custom file at :filepath:
+# Pagy::I18n.load(locale: 'de', filepath: 'path/to/pagy-de.yml')
+#
+# load the "de", "en" and "es" built-in locales:
+# (the first passed :locale will be used also as the default_locale)
+# Pagy::I18n.load({ locale: 'de' },
+#                 { locale: 'en' },
+#                 { locale: 'es' })
+#
+# load the "en" built-in locale, a custom "es" locale,
+# and a totally custom locale complete with a custom :pluralize proc:
+# (the first passed :locale will be used also as the default_locale)
+# Pagy::I18n.load({ locale: 'en' },
+#                 { locale: 'es', filepath: 'path/to/pagy-es.yml' },
+#                 { locale: 'xyz',  # not built-in
+#                   filepath: 'path/to/pagy-xyz.yml',
+#                   pluralize: lambda{ |count| ... } )
+
+
+# I18n extra: uses the standard i18n gem which is ~18x slower using ~10x more memory
+# than the default pagy internal i18n (see above)
+# See https://ddnexus.github.io/pagy/docs/extras/i18n
