How to install apps in haiku..?

I have downloaded zip apps from haikuware.com . I expanded them on desktop using expander . How can I install them now . I have downloaded VLC , abiword , sumit etc…

thank you

There should be a userguide after installation on the desktop…

there is one here too:

most apps you extract/expand to /boot/apps folder

you can choose your own folder and structure for your apps… most programms run in there folders… go to the folder where you expanded the app and run the program…
