Just extract the files is OK.

Then compile stardict-client, strip it and copy it to "/var/www/html/www.stardict.org/".

Needn't now:
=====
Install "auditd", "policycoreutils-python-utils" and "checkpolicy" packages.
Run:
grep stardict-client /var/log/audit/audit.log | audit2allow -M mypol
semodule -i mypol.pp
Then stardict-client will can connect to tcp_socket!

You need to edit php.ini, set:
magic_quotes_gpc = Off
if you are using php version before 5.4.0!

You may need to edit backend.php file, change:
$cmd="./stardict-client ";
to fit your real "stardict-client" file path!
=====

You can create your own language translation!
Such as:
lang.zh_CN.inc
lang.zh_TW.inc
lang.de_DE.inc
lang.ko.inc
lang.ru_RU.inc
lang.sk.inc
lang.uyghur.inc

You can edit "js/lookup.js", search:
// You can translate the next texts!
for more than once and do translation! You can send your changes to me!

You can edit these files and change the website domain name:
mydomain.inc
js/stardict.js
js/initselect.js
js/search-plugin.js
js/lookup.js
files/stardict.src

Look at admin.php for some information!
