 ===== Step 5: install the client =====

-===== Step 6: create a daemon and install it =====
+I've also created a directory called ''/etc/telegram'' that will hold all the configuration and the public key:
+</code>
+# mkdir /etc/telegram
+# chmod u=rwx,g=rx,o=rx /etc/telegram
+# cp tg-server.pub /etc/telegram
+# chmod g=r,o=r,u=r /etc/telegram/tg-server.pub
+</code>
+===== Step 6: create the system user telegramd =====
+In order to run the telegram-daemon as root, you will need to create the user telegramd. I've opted
+to create this user as a system user:
+<code>
+# useradd -M --user-group --system --shell=/bin/false telegramd
+</code>
+Impersonate this user and run the telegram-cli program again, to create a proper configuration file:
+<code>
+telegramd@:~$ /usr/local/share/telegram/telegram-cli -k /etc/telegram/tg-server.pub

+===== Step 7: create a daemon and install it =====
 Telegram-cli has a bug that provokes that, unless ''contact_list'' is the first command issued, no message can be sent through the program. Moreover, there is no way to create a program that just sends a message and ends: the program waits forever even if you run through a pipe. __A more simple version to make automatic notifications from a machine would be desirable.__

+===== Step 8: install the telegram-msg program =====
+After that I've created a ''telegram-msg'' program to just send a message through telegram. The program is pretty simple:
+<code>
+#!/bin/bash
+#
+# telegram-msg - sends a telegram message

+#
