This documentation is not using the current rendering mechanism and is probably outdated. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.

Doing the actual setup

Now fire up a browser and visit your new TYPO3 install – you should get redirected to the install tool in 1-2-3 mode. Fill in the database connection parameters and you should get a list of present databases to choose from (if any exist and are accessible to the user entered). If everything went well up to this point, just continue as usual.

If the 1-2-3 more doesn't work, just go to the regular mode and work your way through the setup.

Try not to create a database from within the install tool, this doesn't work anyway (and it probably never will).
