## Translation
We support many languages, all done by people like you! We make use of free [Weblate's Libre hosting](https://weblate.org/en/donate/) to allow this.
This means if you don't like how a translation was done for your language, you can change it!
Or, you can add a whole new language! Visit [our Weblate project](https://hosted.weblate.org/engage/wifianalyzer/) to help.
