 as ordinary differential equations for the SciML equation solvers.
+## Decapodes.jl: Discrete Exterior Calculus Applied to Partial and Ordinary Differential Equation Systems
+
+[Decapodes.jl](https://github.com/AlgebraicJulia/Decapodes.jl) is a computational physics framework based
+on the Discrete Exterior Calculus (DEC). It uses structure preserving discretization methods from the DEC
+to simulate multiphysics problems. Feature include solving PDEs on triangulated manifolds, a strongly
+typed equation representation that can help ensure correctness of simulations, and compositional methods
+for specifying multi-physics problems.
