+# Serverless Jobs Hello World with Terraform
+
+This example demonstrates how to set up a Scaleway [Serverless Job](https://www.scaleway.com/en/serverless-jobs/) using [Terraform](https://www.terraform.io/).
+
+It builds a custom image locally, pushes this to the Scaleway registry, then creates a job that runs this image on a schedule.
+
+## Requirements
+
+This example assumes you are familiar with how Serverless Jobs work. If needed, you can check [Scaleway's official documentation](https://www.scaleway.com/en/docs/serverless/jobs/quickstart/)
+
+This example uses Terraform. Please set up your local environment as outlined in the docs for the [Scaleway Terraform Provider](https://registry.terraform.io/providers/scaleway/scaleway/latest/docs).
+
+You will also need a Scaleway API key, which can be configured using [Scaleway IAM](https://www.scaleway.com/en/docs/identity-and-access-management/iam/how-to/create-api-keys/). If you are using IAM policies, make sure the key has the permissions: `ServerlessJobsFullAccess`, `ContainerRegistryFullAccess`.
+
+## Setup
+
+Once your environment is set up, you need to export some environment variables to use your API key:
+
+```console
+export TF_VAR_access_key=<your api key>
+export TF_VAR_secret_key=<your secret key>
+export TF_VAR_project_id=<your project ID>
+```
+
+From there, you can run the following to set up your job:
+
+```console
+cd terraform
+
+terraform init
+
+terraform plan
+
+terraform apply
+```
+
+You can then view your Job Definitions in the [Scaleway Console](https://console.scaleway.com/serverless-jobs/jobs).
+
+The Job is set to run on a schedule, once every 5 minutes. Once the next schedule has run, you will see a "Job Run" listed for your Job Definition.
+
+*Note* this job will keep running every 5 minutes, so you need to make sure you delete the job by running:
+
+```console
+cd terraform
+
+terraform destroy
+```
