Manual Translation
1 Download the chosen theme and extract it to a directory of your choice.
2 Access the theme installation directory (the one containing the files screenshot.png and style.css) and look for the folder "lang" or "languages".
3 After finding the folder where the languages are stored, you will see one or more files with the extension .po (e.g., en_EN.po, default.po, themename.po, etc). If a Portuguese translation already exists, you will see a file named pt_BR.po. If this file does not exist, duplicate the default file (e.g., en_EN.po) and rename it to pt_BR.po.
4 Open the file you just renamed (pt_BR.po).
5 To translate a text, simply select the desired line and translate it in the footer of the application.

6Save the file after completing all translations. A file named pt_BR.mo will be generated in the same folder.
7 To finish, just upload both translation files (pt_BR.po and pt_BR.mo) to your server.
