Upload LinkEX to your server
When you have extracted the downloaded archive, you'll find just one file, index.php, this is LinkEX.
Using your favorite FTP client, log in to your webhost, and browse to your document root. Create a directory, eg. "linkex", and upload the index.php file to this folder.
Point your browser to the just created folder, eg. www.yoursite.com/linkex. You will be presented with a welcome screen from LinkEX and a form with a few fields required to install LinkEX.
Username & Password are required to protect your administration interface.
Email is used to send you notifications and password reminder should you forget it.
Website URL is where people should link to.
Website Title is the anchor text people should use to link to the Website URL.
Fill out the form to complete the installation of LinkEX. If the form submits with no errors, you now have a running installation of LinkEX on your site.
The next step is to include the actual links on your site.
Permission error
If you see a "The directory (...) is not writable" message, you should check the permissions on the folder you installed LinkEX in.
It means that LinkEX is not able to create files or folders in the directory, most likely because the permissions are restricted.
