+# Summary
+
+Generalized Proca theories provide a rich landscape to search for solutions to deep, fundamental questions, such as the nature of dark matter. Moreover, strong gravity regimes, such as those around heavy, compact astrophysical objects, permits multimessenger probes of these fundamental fields. These measurements require accurate models in order to search through the huge quantities data. Developing these models for generalized Proca theories is an immense undertaking and usually resorts to numerical methods. 
+
+GRBoondi provides a unified interface for computing the evolution of a specific generalized proca model on any arbitrary analytic background. Given a specific background with known analytic expressions for the metric variables and initial data for the Proca field, GRBoondi numerically computes the time evolution of the Proca field, given user-specified generalized Proca equations of motion. While the full evolution of the background and matter fields in tandem provides the most complete description of the evolution, in many cases, the density of the Proca field is entirely negligible compared to the background curvature. Hence, fixed background evolution routines provide a remarkably good approximation to the full mutual evolution. A core feature of GRBoondi is that it simplifies many of the boiler-plate code required to get a simulation running from scratch. The only additions a user needs to input are the initial conditions, the modifications to the equations of motion above standard Proca, and specify the background functions. GRBoondi will automatically compute various diagnostic quantities and plot files. Moreover, GRBoondi is incredibly modular and modifications to any of the in-built functions is effortless.
+
+The fixed background approximation provides a huge speedup, compared to the full evolution, since only a small fraction of the variables actually require a time integration. Not only do simulations now require far less resources, the speed up can be up to hundreds of times faster. GRBoondi is based on the publicly available NR code GRChombo [@Andrade2021;@Clough2015sqa], which itself is based on the open source adaptive mesh refinement (AMR)-based differential equation solver Chombo [@Adams:2015kgr]. Some minor pieces of GRBoondi are also based off the recently released open source software GRDzhadzha [@Aurrekoetxea2024], which is also based off of GRChombo.
+
+# Statement of need
+
+In practice, any numerical relativity software library can be used to evolve generalized Proca theories. Examples of these include (Einstein toolkit, Cactus, Kranc, LEAN, Canuda, BAM, AMSS-NCKU, PAMR, HAD, SPeC, SpECTRE, NRPy, CosmoGRaPH, GRAMSES, Simflowny, GRAthena++, GRDzhadzha)
+
+While an extensive collection of NR libraries exist, none of them provide a tailored unified interface for studying the vast landscape of generalized Proca theories.
