+How do I add or modify the default user?
+****************************************
+
+The default Cowrie users is called `phil` these days. Having the same
+user always available is an easy way to identify Cowrie so it's recommend to change
+this setup. You can modify it by doing the following::
+
+	$ vi honeyfs/etc/passwd
+
+And edit the userid. Then::
+
+	$ bin/fsctl share/cowrie/fs.pickle
+        fs.pickle:/$ mv /home/phil /home/joe
+
+And then restart Cowrie::
+
+	$ bin/cowrie restart
+
+
+How do I add files to the file system?
+**************************************
+
+The file system meta data is stored in the pickle file. The file
+contents is stored in the `honeyfs` directory.  To add a file, the
+minimum action is to modify the pickle file. Doing this makes the
+file show up in `ls` and other commands. But it won't have any
+contents available. To add file contents, you'll need a file to
+honeyfs.
+
+First add a file system entry, the `1024` here is the file size. The
+`chown` commands only takes numerical uid's, they should match
+entries in `honeyfs/etc/passwd`::
+
+	$ bin/fsctl share/cowrie/fs.pickle
+        fs.pickle:/$ touch /home/phil/myfile 1024
+        fs.pickle:/$ chown 1000:1000 /home/phil/myfile
+
+Then create or copy a file in the `honeyfs`::
+
+	$ cp myfile /honeyfs/home/phil
