Changeing language

i have install xibo on docker windows 10
i downloaded a .mo file for persian language
where i must put the file and how i configure cms to use it?

You don’t need to download the .mo files, you can simply navigate to the CMS Settings -> Regional page.
Set the default language to fa for Persian, the translation isn’t fully complete yet (it is all thanks to community contributions -

If you want to contribute to the translation, then doing that via launchpad is great way.
