        the environment variables. Both `BindEnv` and `AutomaticEnv` will use this
        prefix.
        
       -`BindEnv` takes one or two parameters. The first parameter is the key name, the
       -second is the name of the environment variable. The name of the environment
       -variable is case sensitive. If the ENV variable name is not provided, then
       +`BindEnv` takes one or more parameters. The first parameter is the key name, the
       +rest are the name of the environment variables to bind to this key. If more than
       +one are provided, they will take precedence in the specified order. The name of
       +the environment variable is case sensitive. If the ENV variable name is not provided, then
        Viper will automatically assume that the ENV variable matches the following format: prefix + "_" + the key name in ALL CAPS. When you explicitly provide the ENV variable name (the second parameter),
        it **does not** automatically add the prefix. For example if the second parameter is "id",
        Viper will look for the ENV variable "ID".
