                    ## About This Challenge

                    **Welcome to the ConStellaration Leaderboard**, a community-driven effort to accelerate fusion energy research using machine learning.

                    In collaboration with [Proxima Fusion](https://www.proximafusion.com/), we're inviting the ML and physics communities to optimize plasma configurations for stellarators—a class of fusion reactors that offer steady-state operation and strong stability advantages over tokamaks.

                    This leaderboard tracks submissions to a series of open benchmark tasks focused on:

                    - **Geometrically optimized stellarators**
                    - **Simple-to-build quasi-isodynamic (QI) stellarators**
                    - **Multi-objective, MHD-stable QI stellarators**

                    Participants are encouraged to build surrogate models, optimize plasma boundaries, and explore differentiable design pipelines that could replace or accelerate slow traditional solvers like VMEC++.

                    ### Why It Matters

                    Fusion promises clean, abundant, zero-carbon energy. But designing stellarators is computationally intense and geometrically complex. With open datasets, reference baselines, and your contributions, we can reimagine this process as fast, iterative, and ML-native.

                    ### How to Participate

                    - Clone the [ConStellaration dataset](https://huggingface.co/datasets/proxima-fusion/constellaration)
                    - Build or train your model on the provided QI equilibria
                    - Submit your predicted boundaries and results here to benchmark against others
                    - Join the discussion and help expand the frontier of fusion optimization

                    Let's bring fusion down to Earth—together.
