 SSO Client for OVH
 
+## Usage
+
+OVH SDKs are able to read the `ovh.conf` file and fetch the credentials from it.  
+It also includes the Terraform provider. For instance, you can set up the Terraform provider this way:
+```hcl
+provider "ovh" {
+  endpoint           = "ovh-eu"
+}
+```
+
+Then, run ovh-oauth2cli in the Terraform root directory. You should be able to execute a terraform plan.\
+⚠️ Don't forget to add ovh.conf to your .gitignore file.
+
 ## Installation
 
 ```
-go install github.com/bmassemin/ovh-oauth2cli@latest
+go install github.com/bmassemin/ovh-oauth2cli@v0.0.2
