YunoHost App Update and phpBB Customization

Hi there,

I added the phpBB App to my YunoHost Server. phpBB is up and running and currently, I am setting up the forum.

My question is: If I do customization, e.g. install additional Styles or Language packs, will I run into issues when YunoHost is updating to a newer version of phpBB? Are the any “best practises” for updating a customized phpBB?

Kind regards,
