+base_locale: en
+## All available locales are inferred from the data by default. Alternatively, specify them explicitly:
+# locales: [es, fr]
+## Reporting locale, default: en. Available: en, ru.
+# internal_locale: en
+
+# Read and write translations.
+data:
+  ## Translations are read from the file system. Supported format: YAML, JSON.
+  ## Provide a custom adapter:
+  # adapter: I18n::Tasks::Data::FileSystem
+
+  # Locale files or `File.find` patterns where translations are read from:
+  read:
+    ## Default:
+    - config/locales/%{locale}.yml
+    ## More files:
+    - config/locales/**/*.%{locale}.yml
+    ## Another gem (replace %#= with %=):
+    # - "<%#= %x[bundle show vagrant].chomp %>/templates/locales/%{locale}.yml"
+
+  # Locale files to write new keys to, based on a list of key pattern => file rules. Matched from top to bottom:
+  # `i18n-tasks normalize -p` will force move the keys according to these rules
+  write:
+    ## For example, write devise and simple form keys to their respective files:
+    - ['{blacklight, devise, devise_invitable, generic_work, hyrax, image, simple_form}.*', 'config/locales/\1.%{locale}.yml']
+    ## Catch-all default:
+    - config/locales/%{locale}.yml
+
+  ## Specify the router (see Readme for details). Valid values: conservative_router, pattern_router, or a custom class.
+  # router: conservative_router

+search:
+  ## Paths or `File.find` patterns to search in:
+  # paths:
+  #  - app/
+
+  ## Root directories for relative keys resolution.
+  # relative_roots:
+  #   - app/controllers
+  #   - app/helpers
+  #   - app/mailers
+  #   - app/presenters
+  #   - app/views
+
+  ## Files or `File.fnmatch` patterns to exclude from search. Some files are always excluded regardless of this setting:
+  ##   %w(*.jpg *.png *.gif *.svg *.ico *.eot *.otf *.ttf *.woff *.woff2 *.pdf *.css *.sass *.scss *.less *.yml *.json)
+  exclude:
+    - app/assets/images
+    - app/assets/fonts
+    - app/assets/videos
+
+  ## Alternatively, the only files or `File.fnmatch patterns` to search in `paths`:
+  ## If specified, this settings takes priority over `exclude`, but `exclude` still applies.
+  # only: ["*.rb", "*.html.slim"]
+
+  ## If `strict` is `false`, guess usages such as t("categories.#{category}.title"). The default is `true`.
+  # strict: true
+
+  ## Multiple scanners can be used. Their results are merged.
+  ## The options specified above are passed down to each scanner. Per-scanner options can be specified as well.
+  ## See this example of a custom scanner: https://github.com/glebm/i18n-tasks/wiki/A-custom-scanner-example

+# translation:

+
+## Do not consider these keys missing:
+# ignore_missing:
+# - 'errors.messages.{accepted,blank,invalid,too_short,too_long}'
+# - '{devise,simple_form}.*'
+
+## Consider these keys used:
+# ignore_unused:
+# - 'activerecord.attributes.*'
+# - '{devise,kaminari,will_paginate}.*'
+# - 'simple_form.{yes,no}'
+# - 'simple_form.{placeholders,hints,labels}.*'
+# - 'simple_form.{error_notification,required}.:'
+
+## Exclude these keys from the `i18n-tasks eq-base' report:
+# ignore_eq_base:
+#   all:
+#     - common.ok
+#   fr,es:
+#     - common.brand
+
+## Ignore these keys completely:
+# ignore:
+#  - kaminari.*
+
+## Sometimes, it isn't possible for i18n-tasks to match the key correctly,
+## e.g. in case of a relative key defined in a helper method.
+## In these cases you can use the built-in PatternMapper to map patterns to keys, e.g.:
+#
+# <%# I18n::Tasks.add_scanner 'I18n::Tasks::Scanners::PatternMapper',
+#       only: %w(*.html.haml *.html.slim),
+#       patterns: [['= title\b', '.page_title']] %>
+#
+# The PatternMapper can also match key literals via a special %{key} interpolation, e.g.:
+#
+# <%# I18n::Tasks.add_scanner 'I18n::Tasks::Scanners::PatternMapper',
+#       patterns: [['\bSpree\.t[( ]\s*%{key}', 'spree.%{key}']] %>
