+# GUIDELINES:
+# Each line is a file pattern followed by one or more owners.
+# Owners bear a responsibility to the organization and the users of this
+# application. Repository administrators have the ability to merge pull
+# requests that have not yet received the requisite reviews as outlined
+# in this file. Do not force merge any PR without confidence that it
+# follows all policies or without full understanding of the impact of
+# those changes on build, release and publishing outcomes.
+#
+# The CODEOWNERS file constitutes an agreement amongst organisation
+# admins and maintainers to restrict approval capabilities to a subset
+# of contributors. Modifications to this file result in a modification of
+# that agreement and can only be approved by those with the knowledge
+# and responsibility to publish libraries under the MetaMask name.
+
+# Fallback for all other files
