NexStart menu and hotspot tutorial http://www.winstep.net/help/tutorial/intro.html

(The above are based on NexStart 2.8, NexStart 3.0 (currently in beta) has some of its configuration dialog boxes rearranged to be a bit more sensible.

If you're looking for Workshelf information (Workshelf is the horizontal tabbed shorcut launcher that complements NexStart):

As for Litestep, I know nothing about it but lots of other people here do

I should have mentioned in order to use NextStart you need the NextStart application. If you want to use Workshelf, you need the Workshelf application.

Both can be found either separately or bundled together here: http://www.winstep.net

what did you download for LS? a theme or the program itself?
best idea is to start here: http://students.seattleu.edu/connolb/tutorials/litestep_tutorial/litestep_part_1.html

i dl the LS theme called Fusion

you need the program first. follow the steps in the tutorial in my post above.

Be aware that LiteSTEP is not just a 'program' but is actually a 'shell' for the Operating System, and hence should NOT be treated lightly, or in blissful ignorance.
Read about what it is and what it does BEFORE you try using/installing it.

The same goes for any and every shell replacement...

I did and it worked now i perfer explorer better (cuz im used to it) btw wuts the difference between nextstart and litestep

NextStart: easy to use, can be run on top of explorer, costs money

LiteStep: hard to use for computer novices, can be run as shell ("normal" way of use) or on top of explorer, Open Source but requires more time to learn, most features of any desktop/shell replacements
