i read them but stilll cannot understand how to use it :(
On wiki give a lot of gadgets like cpu,mem etc scripts but where i copy them?
the basic usage is running like $ some_cool_cmd_that_outputs_what_you_need | dzen2 --some-options-about-fonts-and-position in your .xinitrc file. Ready-to-use scripts are here.
You just combine & run them like in example.
