        ```go
        viper.AddRemoteProvider("etcd", "http://127.0.0.1:4001","/config/hugo.json")
        viper.SetConfigType("json") // because there is no file extension in a stream of bytes, supported extensions are "json", "toml", "yaml", "yml", "properties", "props", "prop"
        err := viper.ReadRemoteConfig()
        ```
        
       +#### Consul
       +You need to set a key to Consul key/value storage with JSON value containing your desired config.  
       +For example, create a Consul key/value store key `MY_CONSUL_KEY` with value:
       +
       +```json
       +{
       +    "port": 8080,
       +    "hostname": "myhostname.com"
       +}
       +```
       +
       +```go
       +viper.AddRemoteProvider("consul", "localhost:8500", "MY_CONSUL_KEY")
       +viper.SetConfigType("json") // Need to explicitly set this to json
       +err := viper.ReadRemoteConfig()
       +
       +fmt.Println(viper.Get("port")) // 8080
       +fmt.Println(viper.Get("hostname")) // myhostname.com
       +```
