Viper requires minimal configuration so it knows where to look for config files.
Viper supports JSON, TOML and YAML files. Viper can search multiple paths, but
currently a single Viper instance only supports a single configuration file.
+Viper does not default to any configuration search paths leaving defaults decision
+to an application.
+
+Here is an example of how to use Viper to search for and read a configuration file.
+None of the specific paths are required, but at least one path should be provided
+where a configuration file is expected.
```go
viper.SetConfigName("config") // name of config file (without extension)
viper.AddConfigPath("/etc/appname/") // path to look for the config file in
viper.AddConfigPath("$HOME/.appname") // call multiple times to add many search paths
+viper.AddConfigPath(".") // optionally look for config in the working directory
err := viper.ReadInConfig() // Find and read the config file
if err != nil { // Handle errors reading the config file
panic(fmt.Errorf("Fatal error config file: %s \n", err))
