Manually installed files to display in dash

for adding manually installed program to the dash and launcher you have to write a desktop files for it (which end with .desktop ) .

the desktop file have this form in usual :

[Desktop Entry]
Name=application name
Exec=the command which you have to launch your application 
Comment= a small description for this application 
Icon= the directory for the icon which you want 

this file is a very simple one , there is a lot of options that you can add to it .

then you have to put it into this directory :

/usr/share/applications/

if you want to add an icon for this program add your icon to this directory :

/usr/share/pixmaps

and then configure the .desktop file to user this icon .(in the Icon field )

it will appear in the dash now , or you may have to logout and login again.
