### Working with Environment Variables
Viper has full support for environment variables. This enables 12 factor
applications out of the box. There are four methods that exist to aid working
applications out of the box. There are five methods that exist to aid working
with ENV:
* `AutomaticEnv()`
* `BindEnv(string...) : error`
* `SetEnvPrefix(string)`
* `SetEnvKeyReplacer(string...) *strings.Replacer`
* `AllowEmptyEnvVar(bool)`
_When working with ENV variables, it’s important to recognize that Viper
treats ENV variables as case sensitive._
@ -217,6 +218,10 @@ keys to an extent. This is useful if you want to use `-` or something in your
`Get()` calls, but want your environmental variables to use `_` delimiters. An
example of using it can be found in `viper_test.go`.
By default empty environment variables are considered unset and will fall back to
the next configuration source. To treat empty environment variables as set, use
the `AllowEmptyEnv` method.
#### Env example
