How to setup

1. Place a chest
2. Place a sign attached to the chest. The sign should be in front of / behind / left / right / above the chest
   The format of the sign should be like:
    Line 1: [Interceptor]
    Line 2 (Level of the missile interceptor，3 possible values): Standard, Advanced or Ultra
    Line 3: (LEAVE A BLANK)
