How could I manually translate a template I've downloaded?

Question

This is my second day with wordpress and I would like to translate the whole website to my native language (Portuguese). I've translated a couple buttons and stuff, but it takes me a while to find where it is within the PHP codes, and, a friend of mine who works with wordpress, said it could be dangerous to alter the theme and cherry framework files.

I am looking for a tool/plugin where I can manually translate all the strings, and not use Google translate, as most plugins I've saw. Any tips?

Alright, so I managed to solve my problem with a WordPress plugin called Say What. After installing it, it's pretty simple to use! For instance, I have this string on my template:

<?php _e('Search for: ','cherry');?>"<?php the_search_query(); ?>"

Then, on Say What plugin, all I gotta do is:

Original String = Search for: 
Text Domain = cherry
Replacement string = Buscar por:

It's working great! Thanks!
