Copy the zip file to your desktop or to your home directory.
For example, right-click on the zip-file, and on the menu that
appears, choose "Copy to / Home".

If you copied the file to "Home", open the "Home Folder"
in the file manager from the "Dash Home" menu.

Double-click the zip-file: it will then be opened with the
"Archive Manager".

Extract the "Eq-Diagr" folder to your home directory
(/home/user_name).  Make sure that the "Re-create folders"
and "Overwrite existing files" actions are checked.

Open a terminal (Ctrl-Alt-T). Type:
   cd Eq-Diagr
   chmod a+x *.jar
   exit

Double-clicking on a jar-file will start the corresponding
program (see below about installing java).

If you do NOT wish desktop icons, you may now move the
zip file to trash.  You may also move to trash the folders
"~/Eq-Diagr/Windows-files", "~/Eq-Diagr/Ubuntu-Desktop"
and "~/Eq-Diagr/MacOS-files".


Desktop icons:
==============
Copy or move the files in the folder "Ubuntu-Desktop"
to your desktop. Two files should be on your desktop:
DataBase.desktop  and  Spana.desktop

Open a terminal (Ctrl-Alt-T). Type:
   cd Desktop
   chmod a+x *.desktop
   exit

Now you may move the zip file to trash. You may also move to
trash the subfolders "Windows-files", "Ubuntu-Desktop" and
"MacOS-files".

The icons on the desktop will be updated after you
log-out/log-in, or if resized. You may lock the icons to the
dash home launcher bar by drag and drop on top of
the Dash Home icon.


Java 1.6 or later is needed
===========================
If java is not installed, double clicking on an desktop icon
will result in an error.  You may check this: open a terminal
(Ctrl-Alt-T), and type:
   java -jar /home/_your_name_/Eq-Diagr/Spana.jar
The error message will tell you if java is installed or not.
If java is not installed you will need to install it; type:
   sudo apt-get install default-jre
Once java is installed, the desktop icons will work.
