+
+[SIMple Physics][simple-physics-site] by [@mkhan45] is a set of educational physics
+simulators meant to help students and teachers conduct labs without expensive equipment
+or in person classes. Each simulator uses serializeable graphs, object inspection,
+Lua scripting, and a few other features to help students learn. Currently, there
+is a simulator for mechanics/projectile motion and one for universal gravitation,
+but the goal is to include one for electronics/magnetism and one for waves/optics.
+
+Written in Rust using `ggez`, `specs`, `imgui-rs`, and `nphysics`,
+this project's goals include:
+performance, accessibility/portability, ease of use, and extensibility.
+
+To find out more about the project, visit the site [here][simple-physics-site],
+watch some cool gifs [here][simple-physics-gifs], or read the GitHub page
