+
+[Particular] by [@Canleskis] is a library allowing for simulations of
+N-body gravitational interaction of particles. It aims to be simple
+to integrate in existing game and physics engines, such as [Bevy] or [Rapier].
+See the [demo source code] for the example of an integration (less than 50
+actual lines of code!).
+The [demo] is available on the browser (Chromium-based recommended)
+with various scenes you can interact with.
+
+Particular can be used with [rayon] to leverage multithreading on the
+CPU (`parallel` feature). Although the current algorithm performs well enough
+for most use cases, with a single frame taking around 5 ms with 5000 particles
+on an I9 9900K, future updates will introduce other implementations to allow for
+faster computation of the forces (example: [Barnes-Hut]).
