sitemap.xml how to use with google?

hi

I created a google sitemap, sitemap.xml with sitemap
but how do I use this file? how does google use it?

Did you created it by yourself or with some plugin?

You must submit the file to Google

If you have a Google account (Gmail account), go to the link below, login and then submit your sitemap page:
