 * Building connections between particles and the influence of other particles on these connections.
 * The influence of temperature and other environmental factors on the behavior of particles.
 
+Particles of different types are visualized in different colors. Their properties, presented in the configuration of the world, depend on the type of particle:
+
+1. **Gravity coefficient matrix for unlinked particles** shows whether a particle of one type will attract or repel a particle of another type in the case when they are not linked to each other, and with what force.
+2. **Gravity coefficient matrix for linked particles** shows whether a particle of one type will attract or repel a particle of another type in the case when they are linked to each other, and with what force.
+3. **Connection limit map** shows the maximum number of links for particles of each type.
+4. **Connection limit matrix** shows the maximum number of connections that particles of each type can have with particles of different types.
+5. **Matrix of influence on neighbors links** shows how particles of each type affect the maximum length of links of neighboring particles of different types.

+## Controls
+### 3D
+* `↑`, `↓`, `←`, `→` — move forward, backward, left, right.
+* Rotations are done by dragging.
+
+### 2D
+* `Wheel` — move up and down.
+* `Shift + Wheel` — move left and right.
+* `Ctrl + Wheel` — zoom.
+
+### Adding new particles
+* `Numeric key down + Click` — add a particle with the type corresponding to the number of the key.
+* `1 + click` — add a particle of the first type.
+* `2 + click` — add a particle of the second type.
