+## About us (SixtyFPS GmbH)
+
+We are passionate about software - API design, cross-platform software
+development and user interface components. Our aim is to make developing user
+interfaces fun for everyone: from Python, JavaScript, C++, or Rust developers all the
+way to UI/UX designers. We believe that software grows organically and keeping
+it open source is the best way to sustain that growth. Our team members are
+located remotely in Germany, Finland, and US.
