+# A list of values for the Accept-Language HTTP header used when
+# downloading webpages during URL preview generation. This allows
+# Synapse to specify the preferred languages that URL previews should
+# be in when communicating with remote servers.
+#
+# Each value is a IETF language tag; a 2-3 letter identifier for a
+# language, optionally followed by subtags separated by '-', specifying
+# a country or region variant.
+#
+# Multiple values can be provided, and a weight can be added to each by
+# using quality value syntax (;q=). '*' translates to any language.
+#
+# Defaults to "en".
+#
+# Example:
+#
+# url_preview_accept_language:
+#   - en-UK
+#   - en-US;q=0.9
+#   - fr;q=0.8
+#   - *;q=0.7
+#
+url_preview_accept_language:
+#   - en
