+Using Blackbox without a repo
+===========================
+If the files are copied out of a repo they can still be decrypted
+and edited.  Obviously edits, changes to keys, and such will be lost
+if they are made outside the repo. Also note that commands are most
+likely to only work if run from the base directory (i.e. the parent to
+the keyrings directory).
+
+The following commands have been tested outside a repo:
+
+  * `blackbox_postdeploy`
+  * `blackbox_edit_start`
+  * `blackbox_edit_end`
+
+
