How to install one or more languages ​​in my forum?

Happy Sunday to all. How to install one or more languages ​​in my forum? Sorry for the perhaps trivial question, but I would not like to ruin the forum by making risky changes. I tried to look for this site but I didn't understand much. What is the DISadvantage of installing all the languages ​​available for PHPBB as well as English? Thanks for your attention.

Download the language pack, put it in language folder of your phpbb.
Install from ACP > Customise > Language Packs > Install
Then you can choose langauge from Board Settings.

Here's full method : https://www.phpbb.com/support/docs/en/3 ... uage-pack/

You may also need to translate and install language pack for all extensions, if not available for your language.

I use gtranslate.io.
You can see an example on my forum serontv.com.
