Hi Karom

Everything you need to know is in the Google Webmaster Tools Sitemap guide and Change Googlebot crawl rate.

You can also learn about frequencies and modification information in the Build a sitemap guide as well.

Here are some sitemap generators to help maintain and recrawl your sitemap so it's upto date.

Hope this all helps - good luck!
