fix: edit the specs

 - Handle user custom particle properties (ex: decay, frequency, personality, etc.)
 - Handle additional drawings for the current frame due to custom events (ex: segment between two particles)
 
-## New project
+## How to use in a project
 
 1. Clone lj_rust_template and edit draw.rs
 2. add lj_particle library crate
 3. edit the draw function 
-4. draw
+4. compile
 
+## Fundamental Features
+- [ ] Use a 3D physics engine
+- [ ] Provide hooks to create and update the simulation (onInit, onTick, onCollide, etc.)
+- [ ] Render using box clipping for out of bound particles points
+- [ ] Use an out-of-simulation list of additional points
+- [ ] Render to STDOUT or Redis 
+
+## Future Features 
+
+- [ ] Use a 2D physics engine
+- [ ] Use attractors/repulsors objects
+- [ ] Use OSC to update configuration
