   Getting Started with Checkly Terraform Provider
 ---
 
-# Installing the provider and getting started
-
-1. Create a `versions.tf` terraform config file in your project:
-
-```terraform
-terraform {
-  required_providers {
-    checkly = {
-      source = "checkly/checkly"
-      version = "1.3.0"
-    }
-  }
-}
-
-variable "checkly_api_key" {
-}
-
-variable "checkly_account_id" {
-}
-
-provider "checkly" {
-  api_key = var.checkly_api_key
-  account_id = var.checkly_account_id
-}
-```
-
-2. To use the provider with your Checkly account, you will need an API Key for your Checkly user. Go to the [User Settings: API Keys page](https://app.checklyhq.com/settings/user/api-keys) and click 'Create API Key'. Get your User API Key and add it to your env:
-```bash
-$ export TF_VAR_checkly_api_key=cu_xxx
-```
-
-3. You also need to set your target Account ID, which you can find under your [account settings](https://app.checklyhq.com/settings/account/general). If you don't have access to account settings, please contact your account owner/admin.
-
-
-```bash
-$ export TF_VAR_checkly_account_id=xxx
-```
-
-> ⚠️ If you are still using legacy Account API Keys, you can skip this step. Notice that Account API keys will be deprecated soon.
-
-4. Run `$ terraform providers` in your terminal. The Checkly plugin should be listed.
-
-```bash
-terraform providers
-.
-└── provider[registry.terraform.io/checkly/checkly] ***
-```
-
-5. Create a TF resource config file, for example `main.tf`:
-```terraform
-resource "checkly_check_group" "first-group" {
-  name        = "Group 1"
-  activated   = true
-  muted       = false
-  concurrency = 3
-  locations = [ "eu-west-1" ]
-}
-
-resource "checkly_check" "first-api-check" {
-  name      = "API check 1"
-  type      = "API"
-  activated = true
-  muted     = false
-  frequency = 720
-
-  request {
-    method           = "GET"
-    url              = "https://api.checklyhq.com/public-stats"
-  }
-
-  group_id    = checkly_check_group.first-group.id
-  group_order = 1
-
-}
-```
-
-6. Now run `$ terraform init` to setup a new project. Then use `$ terraform plan` followed by `$ terraform apply` to deploy your monitoring.
+The Checkly Terraform provider enables you to declare your monitoring setup as code using HashiCorp Terraform. You can get started with it in a matter of minutes by following [our step-by-step tutorial](https://www.checklyhq.com/docs/terraform-provider/).
