+## Introduction
+The terraform project will instanciated a devops-stack on Scaleway.
+
+## Installation
+
+Add your credentials to launch the project. At least the following environement variables are required: `SCW_ACCESS_KEY,SCW_ACCESS_KEY,SCW_DEFAULT_ORGANIZATION_ID,SCW_DEFAULT_PROJECT_ID,SCW_DEFAULT_PROJECT_ID`.
+
+We also use an environement variable for the variable PROJECT\_ID called `TF_VAR_PROJECT_ID`
+
+Configure the stack by modifying `inputs.tfvars` (e.g: cluster\_name) and launch the terraform apply with:
+
+If you want to create a Kapsule cluster, you will have to use the scaleway provider in version 2.33.0.
+
+If you modify the base\_domain, be sure to add a new star record that points to the load balancer ip address created by the stack in your domain.
+
+```bash
+terraform init
+terraform apply -var-file inputs.tfvars 
+```
+
+## Usage
+Get the kubeconfig file and the domain name with the following commands:
+
+```bash
+terraform output -raw kubeconfig_file > kubeconfig.json
+terraform output base_domain 
+```
+
+Your application are available at the following address: $APP\_NAME.apps.$CLUSTER\_NAME.$BASE\_DOMAIN.
+e.g: prometheus.apps.devops-stack.51-51-52-52.np.io
+
+For authentication on oidc, users and password are available in the output:
+```bash
+terraform output passwords
+```
+
