Just enter your sitemap url and click ping google, this will ping the google that the sitemap is updated and your links can get indexed.
Pinging a sitemap is a bit different than just providing it in the robots.txt -- by pinging, you're actively flagging a change in the sitemap file. If you're keen on having new content indexed quickly, that's a good practice.
