Sumo theme supports the following languages:

• English (en)
• German (de)
• Spanish (es)
• French (fr)
• Finnish (fi)

English is set as the default language, but you can easily switch languages by defining it in your config.json. You can modify it by going to the Design page in your Micro.blog Dashboard. Click Open Theme and choose config.json. Below, you can see the default config.json in its entirety (it really is that short). Change en to your preferred language.
