Custom string translation


I would like to have the possibility to translate custom string I added, using the theme .pot file.
For example, let’s say I added a string _e('Hello world') in the front-page.php file.
I want to translate it in Italian. I downloaded the it_IT.po file and saved it inside sagetheme/lang then, inside it, I added the translation of the string:

#: front-page.php:129
msgid ""
"Hello world"
msgstr ""
"Ciao mondo "

But it actually doesn’t work.


Thank you!
