Search engines and robots.txt
Since the birth of internet search engines, the robots.txt file has been how webmasters could let search engines like Google know what content should get crawled and indexed. However, as part of Google Sitemaps, later named XML Sitemaps Protocol, the usage was expanded with Sitemaps Autodiscovery. It is now possible for webmaster to direct search engines to the website XML sitemap. The moment a search engine has found your website and the robots.txt file, it will also know where to find your XML sitemap.

Submit your XML sitemaps
In the beginning, XML sitemaps submission required you had created and verified a Google Webmaster Tools account. You also had to submit your sitemap files manually. Now, instead of submitting XML sitemaps to all search engines individually, you can be done with them all in seconds.

After crawling your website and creating the XML sitemap, the sitemap generator program can create the robots.txt file with correct and complete path to your XML sitemap.

As see from above, to add XML sitemaps autodiscovery to a robots.txt file, add the fully qualified XML sitemap file path like this: Sitemap: http://www.example.com/sitemap.xml.
