1. find out where your 'icewm' directory is. in that dir resides the themes dir
	hint: my own icewm dir is in /usr/local/lib/X11/icewm/themes/

2. copy (as super user) the downloaded file to the themes dir
	hint: - (again, in my case) go to the directory where the downloaded file is and do 'cp -R ergologic_1.0.tar.gz  /usr/local/lib/X11/icewm/themes/'

3. cd to the 'themes' dir in the 'icewm' directory and unpack the file you just copied with 'tar zxvf ergologic_1.0.tar.gz'

the theme will be unpacked and put in the directory 'ergologic'. restart your icewm and the theme is available.
