Prepare your website for multilingual content by adding available languages, specifying translatable content types, and adding a language switcher before configuring the module.
Determine which content types will be translated: pages, comments, custom blocks, taxonomy terms, and user accounts. For each selected content type, specify which subtypes or fields should be translated.
To configure translatable content:
Navigate to Configuration > Regional and language > Content language and translation.
Select the desired content types for translation from the list.
Go through the table and enable Translatable at the start of each row.
Save your changes by clicking Save configuration.
