+about:
+  summary: Gyrokinetic Spectral Solver of Plasma Turbulence
+  description: |
+    GKX is a JAX-native gyrokinetic solver designed for differentiability,
+    high-performance accelerator execution, and advanced stellarator
+    optimization.
+    The code employs a Hermite-Laguerre velocity space, Fourier perpendicular
+    coordinates, and field-aligned flux-tube geometry to simulate linear and
+    nonlinear electrostatic and electromagnetic turbulence in magnetized
+    plasmas.
