For Windows and for Linux there are 2 Source-Downloads. For this you need an existing environment with an installed Apache, mySQL and php5 (AMP).
To install i-doit you just need to copy the un-packed data into a directory in your web server. Then you just have to access that directory to start the easy-to-use setup of i-doit.

For an automated Windows setup including the essential AMP Environment, you need to install the Microsoft Visual C++ runtime files. A package of these files has been made available by Microsoft here.

The following standard logins are available after a successfull i-doit setup:

Username	Password	Permissions
admin	admin	All
reader	reader	Read-only
editor	editor	Read and write
author	author	New, read and write
archivar	archivar	Read and delete

If you want to install an update for i-doit, extract the corresponding archive into your i-doit directory. The update is startet over the following URL then: http://idoit-server/idoit/updates - where /idoit/ stands for the www-directory your i-doit is reachable.
