So you’re helping out to translate syncthing on [Transifex](https://www.transifex.com/projects/p/syncthing/)? Thanks! And you want to use your new translations with with syncthing, of course. Here’s how to do that.
First of all, you need [syncthing v0.9.0-beta2](https://github.com/calmh/syncthing/releases/tag/v0.9.0-beta2) or newer. Beware that this is currently a bit more beta than usual and doesn’t interoperate at all with v0.8.x. See [v0.9.0 beta testing](https://forum.syncthing.net/t/v0-9-0-beta1-testing/565) for some pointers.
Then you go to Transifex, navigate to the project and click the “GUI strings” resource. You’ll get a dialog where you can click “Download for use”. It should look something like this:
You’ll get a file called something like `for_use_syncthing_gui_sv.json` (for Swedish, `sv`). You need to rename this file to `lang-sv.json` (or some other `lang-xx.json` for another language code). Then you must create a directory somewhere, we’ll assume it’s called `translation` for now, and put the file here. So you should now have a directory containing only the translation file, called `lang-sv.json`.
You now need to start syncthing and tell it where it can find additional, non-bundled resources. You do this by giving it the `STGUIASSETS` environment variable, pointing to the directory you just created with the translation file in it. I’ll just call it `translation` here but it could be a path like `/tmp/download` or `c:\syncthingstuff`. Start syncthing like this (on Linux/MAC):
`$ STGUIASSETS=translation syncthing`
Like this on Windows, assuming the translation file is in `C:\syncthing\translation`:
```
C:\syncthing> set STGUIASSETS=translation
C:\syncthing> syncthing
```
Now navigate to the GUI. You’ll get it in english as usual. You now need to add a parameter to the URL to let syncthing know that it should load another language. The parameter should be `#?lang=sv` (yes, both a # and a ?). So if your normal URL is
`http://localhost:8080/`
Then to use the file `lang-sv.json` you change the URL to
`http://localhost:8080/#?lang=sv`
This’ll all get a bit less tedious once there is a way to change the language from within the GUI…
