-Load and visualize aircraft FDM metrics from JSBSim XML files inside Blender
+JSBSim-Viewer is an extension that lets you import and visualize the spatial layout of [JSBSim](https://github.com/JSBSim-Team/jsbsim) flight dynamics model (FDM) XML data. It reads the XML structure and plots the defined nodes, points, and reference locations in 3D space, allowing you to explore the aircraft’s configuration visually.
+
+This is useful for:
+
+- Inspecting the geometric and reference layout of JSBSim aircraft models
+- Debugging or understanding FDM XML configurations
+- Visualizing how aerodynamic and structural points are positioned relative to each other
