+  Creates and manages a Google Spanner Instance.
+---
+
+# google\_spanner\_instance
+
+Creates and manages a Google Spanner Instance. For more information, see the [official documentation](https://cloud.google.com/spanner/), or the [JSON API](https://cloud.google.com/spanner/docs/reference/rest/v1/projects.instances).
+
+## Example Usage
+
+Example creating a Spanner instance.
+
+```hcl
+resource "google_spanner_instance" "main" {
+  config       = "regional-europe-west1"
+  display_name = "main-instance"
+  name         = "main-instance"
+  num_nodes    = 1
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `config` - (Required) The name of the instance's configuration (similar but not
+   quite the same as a region) which defines defines the geographic placement and
+   replication of your databases in this instance. It determines where your data
+   is stored. Values are typically of the form `regional-europe-west1` , `us-central` etc.
+   In order to obtain a valid list please consult the
+   [Configuration section of the docs](https://cloud.google.com/spanner/docs/instances).
+
+* `display_name` - (Required) The descriptive name for this instance as it appears
+   in UIs. Can be updated, however should be kept globally unique to avoid confusion.
+
+- - -
+
+* `name` - (Optional, Computed) The unique name (ID) of the instance. If the name is left
+    blank, Terraform will randomly generate one when the instance is first
+    created.
+
+* `num_nodes` - (Optional, Computed) The number of nodes allocated to this instance.
+   Defaults to `1`. This can be updated after creation.
+
+* `project` - (Optional) The project in which the resource belongs. If it
+    is not provided, the provider project is used.
+
+## Attributes Reference
+
+No additional attributes are computed other than those defined above.
+
+## Import
+
+Instances can be imported using their `name` and optionally
+the `project` in which it is defined (Often used when the project is different
+to that defined in the provider), The format is thus either `{instanceId}` or
+`{projectId}/{instanceId}`. e.g.
+
+```
+$ terraform import google_spanner_instance.master instance123
+
+$ terraform import google_spanner_instance.master project123/instance456
+
+```
