@ -131,7 +131,8 @@ You can handle the specific case where no config file is found like this:
```go
if err := viper.ReadInConfig(); err != nil {
if _, ok := err.(viper.ConfigFileNotFoundError); ok {
var errNotFound viper.ConfigFileNotFoundError

// Config file not found; ignore error if desired
} else {
// Config file was found but another error was produced
