Unclear installation instruction

[webbird]

When I read the installation wiki page, it was not clear to me that I had to install syncdata into the CMS root directory. Installing it somewhere else causes errors when the installer tries to read the config.php.

Thank you for this hint!

I've done some changes you may wish to review.
