sitemap.xml

Tom, Since I don’t know what I am doing :?, I looked at my robots.txt file on my web site. I assume it should have keywords in it for search engines to find? or, is it supposed to thave web addresses for each of my web pages? Anyway, this is all thats in it at this time…
User-agent: *
Disallow: /log
Disallow: /xxx
I have no idea what it means.
Thanks,
Bill
