+Alternatively (or in addition), the path to a specific config file,
+rather than to a directory containing config files, can be provided.

+viper.SetConfigFile("$HOME/customconfig.toml") // explicitly add a specific config file
+err := viper.ReadInConfig() // read the config file
+if err != nil { // Handle errors reading the config file

 Viper supports the ability to have your application live read a config file while running.
