+## Example Usage - searching for projects about to be deleted in an org
+
+```hcl
+data "google_projects" "my-org-projects" {
+  filter = "parent.id:012345678910 lifecycleState:DELETE_REQUESTED"
+}
+
+data "google_project" "deletion-candidate" {
+   project_id = "${data.google_projects.my-org-projects.projects.0.project_id}"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `filter` - (Optional) A string filter as defined in the [REST API](https://cloud.google.com/resource-manager/reference/rest/v1/projects/list#query-parameters).
+
+
+## Attributes Reference

+
+* `projects` - A list of projects matching the provided filter. Structure is defined below.
+
+The `projects` block supports:
+
+* `project_id` - The project id of the project.
