After WarpIN has been installed itself, it can install WarpIN archives.

WarpIN archives have the .WPI file extension and a special format which is not compatible with other archive formats (e.g. ZIP or RAR). Because WarpIN offers features that other archiving software does not provide for, we have introduced our own format instead.

Since WarpIN is associated with *.WPI files, you can simply double-click on an archive to have WarpIN install it.

After this, a window should open which is pretty similar what you might be used to with other software installers:

Before an application can be installed, you have to give WarpIN some information which files to install, where to install them, whether to create WPS objects, etc. This is done by entering information on the pages and pressing the "Next" button on the bottom right. You can switch back to the previous page by pressing the "Back" button. What exactly is displayed on these pages depends on what the creator of the archive wanted you to see, so there's no general information we can give you here.

In any case however, after all the information has been gathered, the installation process will begin.
