-- `The step function efficiently computes the next step towards a target node within a specified distance limit.'
+- `The step function efficiently computes the next step towards a target node within a specified distance limit.`
+
+### Usage 2D Space
+
+Suppose you have two nodes representing positions in a 2D space:
+- `node0` at coordinates `(0, 0)`
+- `node1` at coordinates `(5, 5)`
+
+You want to compute the next step from `node0` towards `node1` while limiting the maximum distance to 3 units.
+
+```python
+# Define the nodes
+node0 = Node(0, 0)
+node1 = Node(5, 5)
+
+# Compute the next step within a distance limit of 3 units
+next_step = step_from_to(node0, node1, limit=3)
+
+# Output the coordinates of the next step
+print("Next Step Coordinates:", next_step.coord) 
+```
