 ## Stanford Town Game
 
-执行入口为：`python3 run_st_game.py "Host a activity"`   
+### 后端服务启动
+执行入口为：`python3 run_st_game.py "Host a open lunch party at 13:00 pm" "base_the_ville_isabella_maria_klaus" "test_sim" 10`   
 
 `idea`为用户给第一个Agent的用户心声，并通过这个心声进行传播，看最后多智能体是否达到举办、参加活动的目标。  
+
+### 前端服务启动
+进入`generative_agents/environment/frontend_server`，使用`~~python manage.py runserver~~`启动前端服务。
