+# Scheduled Cloud Asset Inventory Export to Bigquery
+
+This example shows how to leverage [Cloud Asset Inventory Exporting to Bigquery](https://cloud.google.com/asset-inventory/docs/exporting-to-bigquery) feature to keep track of your organization wide assets over time storing information in Bigquery.
+
+The data stored in Bigquery can then be used for different purposes:
+
+- dashboarding
+- analysis
+
+This example shows a export to Bigquery scheduled on a daily basis. 
+
+The resources created in this example are shown in the high level diagram below:

+
+## Running the example
+
+### Prerequisites
+Ensure that you grant your account one of the following roles on your project, folder, or organization.
+ - Cloud Asset Viewer role (roles/cloudasset.viewer)
+ - Owner primitive role (roles/owner)
+
+Clone this repository, specify your variables in a `terraform.tvars` and then go through the following steps to create resources:
+
+- `terraform init`
+- `terraform apply`
+
+Once done testing, you can clean up resources by running `terraform destroy`. To persist state, check out the `backend.tf.sample` file.
+
+## Testing the example
+
+You can now run queries on the data you exported on Bigquery. Here you can find some explample of queries you can run.
+
+You can also create a dashborad connecting [Datalab](https://datastudio.google.com/) or any other BI tools of your choice to your Bigquery datase..
