You may want to try using Google search to find some tutorials or look for someone here on the forum that has experience with the script.
its pretty simple actually, just follow the instruction. upload the files on your server and run the installation process. phpLD has a forum where yuo can find info and ask for support from members if needed. if yuo still have problem, then there are people on the services forum who offer script installation service which would be the last thing to consider
It's pretty simple, just go to youdomain.com/phpLD/install, it will guide you through anything Greetings AllOutAnime
