# Output Configuration
Outputs define values that will be highlighted to the user
when Terraform applies, and can be queried easily using the
[output command](/docs/commands/output.html). Output usage
is covered in more detail in the
[getting started guide](/intro/getting-started/outputs.html).
This page covers configuration syntax for outputs.
Terraform knows a lot about the infrastructure it manages.
Most resources have a handful or even a dozen or more attributes
associated with it. Outputs are a way to easily extract
information.
This page assumes you're familiar with the
[configuration syntax](/docs/configuration/syntax.html)
already.
## Example
An output configuration looks like the following:
```
output "address" {
value = "${aws_instance.web.public_dns}"
}
```
## Description
The `output` block configures a single output variable. Multiple
output variables can be configured with multiple output blocks.
The `NAME` given to the output block is the name used to reference
the output variable.
Within the block (the `{ }`) is configuration for the output.
These are the parameters that can be set:
* `value` (required, string) - The value of the output. This must
be a string. This usually includes an interpolation since outputs
that are static aren't usually useful.
## Syntax
The full syntax is:
```
output NAME {
value = VALUE
}
```
