+Import SSH keys
+===============
+
+[◀ Go back to main README](../README.md)
+
+Description
+-----------
+
+This script imports public SSH keys (files with extension "`pub`") into
+local store for user authentication.
+
+Requirements and installation
+-----------------------------
+
+Just install the script:
+
+    $ScriptInstallUpdate ssh-keys-import;
+
+Usage and invocation
+--------------------
+
+Copy files with extension "`pub`" containing public SSH keys for your device.
+Then run the script:
+
+    / system script run ssh-keys-import;
+
+Starting with an `authorized_keys` file you can split it on a shell:
+
+    while read type key name; do echo $type $key $name > $name.pub; done < authorized_keys
