You need to upload the folder to a web-server that has PHP enabled.
To setup the basic authentication please edit index.php, you need to change these two fields:
This will give you a login screen for the admin panel:
You also need to enter your server IP, port and RCON password in rcon.php:
The drop-down lists can be edited in Notepad or Excel, maps must be maps (it will send "changelevel") and modes must be executables (it will send "exec").
## Optional ##
If you want to customize the buttons for quick commands like
Bot Kick and
Restart Game you need to edit the HTML in rcon.php and Javascript in script.js. I just used the ones our clan uses the most, might be enough for most people.
