I have a website that has different language versions to it, like, English, Spanish, French, German. I want to prepare the sitemap.xml for my website. How should I add the urls to my sitemap for these different versions?

Ex: w w w . m y s i t e . c o m/en/..... for english
w w w . m y s i t e . c o m/fr/.... for french, etc.

Keeping the root static, should I place the links for all of them respectively? Will this help the Search Engine to index all my pages with different language options?

Kindly suggest me, I will be very obliged. Thanks in advance.

Bye.
