+===============================================================================
+
+Note that the default application should be to set up a public key
+infrastructure at your site and use keys and certificates genereated by these.
+
+In oder to use the just generated files in your BSP for testing purpose or if
+you do not intend to use real authentification, follow the instructions below. 
+
+Place the key and certificate file in your platform-dir's config/ folder:
+
+  cp rauc-openssl-ca/private/rauc.key.pem <platform-dir>/config/rauc/rauc.key.pem
+  cp rauc-openssl-ca/rauc.cert.pem <platform-dir>/config/rauc/rauc.cert.pem
+
+Place the keyring file in your platform-dir's projectroot/ folder:
+
+  cp rauc-openssl-ca/ca.cert.pem <plaform-dir>/projectroot/etc/rauc/ca.cert.pem
+
+===============================================================================
