+# Distro-specific keys can be added to this package in two ways:
+#
+#   1) In a .bbappend, add .gpg and/or .asc files to SRC_URI and install them to
+#      ${D}${datadir}/opkg/keyrings/ in a do_install:append function. These
+#      files should not be named 'key-$name.gpg' to ensure they don't conflict
+#      with keys exported as per (2).
+#
+#   2) In a .bbappend, distro config or local.conf, override the variable
+#      OPKG_KEYRING_KEYS to contain a space-separated list of key names. For
+#      each name, 'gpg --export $name' will be ran to export the public key to a
+#      file named 'key-$name.gpg'. The public key must therefore be in the gpg
+#      keyrings on the build machine.
