 An implementation of Craig Reynolds's Boids flocker model. Agents (simulated birds) try to fly towards the average position of their neighbors and in the same direction as them, while maintaining a minimum distance. This produces flocking behavior.
 
-This model tests Mesa's continuous space feature, and uses numpy arrays to represent vectors. It also demonstrates how to create custom visualization components.
-
-## Installation
-
-To install the dependencies use pip and the requirements.txt in this directory. e.g.
-
-```
-    $ pip install -r requirements.txt
-```
+This model tests Mesa's continuous space feature, and uses numpy arrays to represent vectors.
 
 ## How to Run
 
-* To launch the visualization interactively, run ``mesa runserver`` in this directory. e.g.
-
-```
-$ mesa runserver
-```
-
-or
-
-Directly run the file ``run.py`` in the terminal. e.g.
-
-```
-    $ python run.py
-```
-
-* Then open your browser to [http://127.0.0.1:8521/](http://127.0.0.1:8521/) and press Reset, then Run.
+* To launch the visualization interactively, run ``solara run app.py`` in this directory.It will automatically open a browser page.
