Although you can add the Transmission add-on via Programs>Get More\\
this does not really install the transmission-daemon app.

To setup, ssh into your pi then\\
  *''sudo apt-get install transmission-daemon''
To get it to run at startup\\
  *''sudo update-rc.d transmission-daemon defaults''

** Note: this does not work as transmission overwrites the config file on start/stop**\\
//
To enable logins on your local network only, edit the settings via
  *''sudo nano /etc/transmission-daemon/settings.json''
and change the rpc-whitelist from
  *''"127.0.0.1"'' to ''"127.0.0.1,192.168.*.*"'' following your subnet\\
Finally
  *''sudo service transmission-daemon restart'' to apply the new settings\\
//\\
**Finally got it to work by ...**\\
  *Created a modified ''settings.json'' as ''settings.json.mod'' with whitelist,watch dir etc
  *Added ''cp /etc/transmission-daemon/settings.json.mod /etc/transmission-daemon/settings.json'' and ''service transmission-daemon reload'' in file ''/etc/rc.local'' so that transmission reloads my modified configuration on boot.
