[TYPO3] Meta Tags Extension Nightmare

[IceKat]

Hi,

I'm totally new to typo3 and have inherited it via a roundabout way. I need to put meta tags in to a site which is already up and have 3 days of searching and 2 mailing list help requests I found the extension to use them but now all I get is:
  <meta name="description" content="{$plugin.meta.description}" />
  <meta name="keywords" content="{$plugin.meta.keywords}" />
  <meta name="robots" content="{$plugin.meta.robots}" />
  <meta name="copyright" content="{$plugin.meta.copyright}" />
  <meta http-equiv="content-language" content="{$plugin.meta.language}" />
  <link rev="made" href="mailto:{$plugin.meta.email}" />
  <meta http-equiv="reply-to" content="{$plugin.meta.email}" />
  <meta name="author" content="{$plugin.meta.author}" />
  <meta name="distribution" content="{$plugin.meta.distribution}" />
  <meta name="rating" content="{$plugin.meta.rating}" />
  <meta name="revisit-after" content="{$plugin.meta.revisit}" />
  <meta name="DC.Description" content="{$plugin.meta.description}" />
  <meta name="DC.Subject" content="{$plugin.meta.keywords}" />
  <meta name="DC.Rights" content="{$plugin.meta.copyright}" />
  <meta name="DC.Language" scheme="NISOZ39.50" content="{$plugin.meta.language}" />
  <meta name="DC.Creator" content="{$plugin.meta.author}" />
  <link rel="schema.dc" href="http://purl.org/metadata/dublin_core_elements" />
I put meta keywords and description in to the page where this code was viewed from (the source) but this is all I get whether the text is in there or not. I also tried a german tutorial from youtube which I was able to follow because of the visuals but still can't get it. How can I put custom meta tags for each page of the site? How can I disable the DC.Description tag and others I don't want?

Can someone please help me out or point me to a place which actually has the instructions in English? Most of what I find online is in German which doesn't help. Thanks in advance...

IceKat.
