How do I get started with phpMailer?

[ICHaps]

Hello.

May I enquire how I can get started with phpMailer?
I've downloaded the zip file and placed it on my site.

Now I haven't got a clue how to configure it.

In the phpMailer file it has:

public $ErrorInfo = '';
public $From = '';
public $FromName = '';
public $Sender = '';
public $Subject = '';
public $Body = '';
public $AltBody = '';
public $Ical = '';

Is this where I place my site's email address and sender's name, and recipients email address?

Also (out of interest) if there is a web developer reading this, could you assist?

Thanks.
