 ### From Source
 
 ```bash
 git clone https://git.ezscale.cloud/EZSCALE/terraform-provider-virtfusion.git
-cd terraform-provider-virtfusion
-go install .
+cd terraform-provider-virtfusion && go install .
 ```
 
-Then configure `~/.terraformrc` for local development:
+Then add dev_overrides to `~/.terraformrc`:
 
-```hcl
+```bash
+cat >> ~/.terraformrc <<'EOF'
 provider_installation {
   dev_overrides {
-    "registry.terraform.io/EZSCALE/virtfusion" = "/path/to/your/gopath/bin"
+    "registry.terraform.io/EZSCALE/virtfusion" = "${GOPATH}/bin"
   }
   direct {}
 }
+EOF
 ```
 
 ## Quick Start
 
+**1. Set your credentials:**
+
+```bash
+export VIRTFUSION_ENDPOINT="https://cp.example.com"
+export VIRTFUSION_API_TOKEN="your-api-token"
+```
+
+**2. Create `main.tf`:**
+
 ```hcl
 terraform {
   required_providers {

-variable "virtfusion_api_token" {

+provider "virtfusion" {}
 
+data "virtfusion_servers" "all" {}
+
+output "server_count" {
+  value = length(data.virtfusion_servers.all.servers)
+}
+```
+
+**3. Run it:**
+
+```bash
+terraform plan
+```
+
+The provider reads `VIRTFUSION_ENDPOINT` and `VIRTFUSION_API_TOKEN` from the environment. You can also set them directly in the provider block:
+
+```hcl
 provider "virtfusion" {
   endpoint  = "https://cp.example.com"
   api_token = var.virtfusion_api_token
 }
 ```
 
-The provider can also be configured using environment variables:
-
-```bash
-export VIRTFUSION_ENDPOINT="https://cp.example.com"
-export VIRTFUSION_API_TOKEN="your-api-token"
-```
-
