The first question I have to ask is if you want to use the AutoDJ or not?

First I'll explain on how to broadcast live only:
First make sure your server is turned on:

Then go to "Quick Links" and use the details under "autoDJ is not running" to connect:

That's all folks! Happy Streaming!

If you want to use the AutoDJ, pick up here!
First make sure it is enabled, 
While we are in settings you can change some basic settings
Under Stream:

Don't forget your genre under AutoDJ:

Some servers might also require your stream name to be changed under Mount Points:

Press update and there we go!

Okay now our settings are correct we can go on.
First of all we have to upload songs!
Open "Files"
If you prefer FTP, those details are under "Quick Links".
Make sure you are in the folder "Media"

Press upload:

Select your files:

And wait till it is finished...

Now this is done we can close the upload dialog and press return to go back.

Now we need to go to Media to add the songs to our playlists:

Select the songs you like and drag them to one of the playlists on the left hand side.

By default we have 3 rotations, the more heavy the more it will play that song.
Press return and prepare for the magic moment!
Press start and there we go!

What's next?
Now we are streaming it is time to dive into Centova Cast.
If you want to connect live you can find your details under "Quick Links", if your server supports DJ accounts (all types excpect SHOUTcast v1) you don't even have to turn off the AutoDJ to go live.
Got a website? Then "Widgets" might be a nice page for you!
Want to plan in shows? Different rotations? Then the playlists feature is what you are looking for!
Last but not least: freaked on statistics? Yes Centova provides those too! (Even in Excel for the die hards)
