+
+# Terraform Provider
+
+The terraform provider exposes resources to access state meta data
+for Terraform outputs from shared infrastructure.
+
+The terraform provider is what we call a _logical provider_. This has no
+impact on how it behaves, but conceptually it is important to understand.
+The terraform provider doesn't manage any _physical_ resources; it isn't
+creating servers, writing files, etc. It is used to access the outputs
+of other Terraform states to be used as inputs for resources.
+Examples will explain this best.
+
+Use the navigation to the left to read about the available resources.
+
+## Example Usage
+
+```
+# Shared infrastructure state stored in Atlas
+resource "terraform_remote_state" "vpc" {
+    backend = "atlas"
+    config {
+        path = "hashicorp/vpc-prod"
+    }
+}
+
+resource "aws_instance" "foo" {
+    # ...
+    subnet_id = "${terraform_remote_state.vpc.output.subnet_id}"
+}

 you can expose things such as VPC IDs, subnets, NAT instance IDs, etc. through

 In the future, we'd like to extend the remote state system to allow some
 minimal locking functionality, but it is a difficult problem without a
 central system that we currently aren't focused on solving.
