Hello I did the translations…

Hello I did the translations to Spanish for Sitemap Generator plugin by Marco Beierer, he´s asking me to send him a file but I don´t know how to put all my translations in a file. The translations are on the following link: https://translate.wordpress.org/projects/wp-plugins/mb-sitemap-generator/stable-readme/es/default?page=3 but they continue to appear as “waiting”.

Can someone help me?
