-# terraform-google-scheduled-function
+# Terraform Google Scheduled Functions Module
+This modules makes it easy to set up a scheduled job to trigger events/run functions.
+
+## Usage
+You can go to the examples folder, however the usage of the module could be like this in your own main.tf file:
+
+```hcl
+module "scheduled-function" {
+  source  = "terraform-google-modules/scheduled-functions/google"
+  version = "0.1.0"
+  project_id   = "<PROJECT ID>"
+  job_name="<NAME_OF_JOB>"
+  schedule="<CRON_SYNTAX_SCHEDULE"
+  function_entry_point="<NAME_OF_FUNCTION>"
+  function_source_directory="<DIRECTORY_OF_FUNCTION_SOURCE>"
+  name="<RESOURCE_NAMES>"
+  region="<REGION>"
+}
+```
+
+Then perform the following commands on the root folder:
+
+- `terraform init` to get the plugins
+- `terraform plan` to see the infrastructure plan
+- `terraform apply` to apply the infrastructure build
+- `terraform destroy` to destroy the built infrastructure
+
+[^]: (autogen_docs_start)

+## Requirements
+### Terraform plugins
+- [Terraform](https://www.terraform.io/downloads.html) 0.11.x
+- [terraform-provider-google](https://github.com/terraform-providers/terraform-provider-google) plugin v2.1
+
+### App Engine
+Note that this module requires a App Engine being configured in the specified project/region. 
+This is because Google Cloud Scheduler is dependent on the project being configured with App Engine.
+Documentation on the App Engine dependency is here: https://cloud.google.com/scheduler/docs/ 
+
+### Configure a Service Account
+In order to execute this module you must have a Service Account with the following roles.
+
+- roles/storage.admin
+- roles/pubsub.editor
+- roles/cloudscheduler.admin
+- roles/cloudfunctions.developer
+- roles/iam.serviceAccountUser
+
+
+### Enable API's
+In order to operate with the Service Account you must activate the following API on the project where the Service Account was created:
+
+- Cloud Scheduler API - cloudscheduler.googleapis.com
+- Cloud PubSub API - pubsub.googleapis.com
+- Cloud Functions API - cloudfunctions.googleapis.com
+
+## Install
+
+### Terraform
+Be sure you have the correct Terraform version (0.11.x), you can choose the binary here:
+- https://releases.hashicorp.com/terraform/
+
+## Testing and documentation generation
+
+### Requirements
+- [docker](https://docker.com)
+- [terraform-docs](https://github.com/segmentio/terraform-docs/releases) 0.6.0
+
+### Integration test
+##### Terraform integration tests
+It is recommended to to run the integration tests via docker. To do so, run `make test_integration_docker`. In containers, this will
+- Perform `terraform init` command
+- Perform `terraform get` command
+- Perform `terraform validate` command
+- Perform `terraform apply -auto-approve` command and check that it has created the appropriate resources
+- Perform `terraform destroy -force` command and check that it has destroyed the appropriate resources
+
+### Autogeneration of documentation from .tf files
+Run
+```
+make generate_docs
+```
+
+### Linting
+The makefile in this project will lint or sometimes just format any shell,
+Python, golang, Terraform, or Dockerfiles. The linters will only be run if
+the makefile finds files with the appropriate file extension.
+
+All of the linter checks are in the default make target, so you just have to
+run
+
+```
+make -s
+```
+
+The -s is for 'silent'. Successful output looks like this
+
+```
+Running shellcheck
+Running flake8
+Running gofmt
+Running terraform validate
+Running hadolint on Dockerfiles
+Test passed - Verified all file Apache 2 headers
+```
+
+The linters
+are as follows:
+* Shell - shellcheck. Can be found in homebrew
+* Python - flake8. Can be installed with 'pip install flake8'
+* Golang - gofmt. gofmt comes with the standard golang installation. golang
+is a compiled language so there is no standard linter.
+* Terraform - terraform has a built-in linter in the 'terraform validate'
+command.
+* Dockerfiles - hadolint. Can be found in homebrew
