 ## Terraform module for deploy kubernetes infrastructure
 This module use OpenStack API
 
-## For using run:
-```bash
-git clone https://github.com/ptsgr/terraform-openstack-kubernetes.git
-cd terraform-openstack-kubernetes
-terraform init # for update dependence
-terraform apply # for run module
-```
 ## To use the module you must enter the parameters
 ```bash
-TF_VAR_cloud_user_name = "your username"
-TF_VAR_cloud_user_pass = "your password"
-TF_VAR_cloud_auth_url    = "openstack url"
-TF_VAR_cloud_tenant_id ="openstack project name"
-TF_VAR_external_network_name = "external network name"
-TF_VAR_cloud_network_id = "internal network id"
-TF_VAR_cluster_VIP = "false" # default = false
+cloud_user_name = "your username"
+cloud_user_pass = "your password"
+cloud_auth_url    = "openstack url"
+cloud_tenant_id ="openstack project name"
+external_network_name = "external network name"
+cloud_network_id = "internal network id"
+cluster_VIP = "false" # default = false
 #cluster_VIP is cluster virtual ip, by default use keepalived.
 
-TF_VAR_cluster_name = "cluster name"
-TF_VAR_vms_image_id = "image id"
-TF_VAR_vms_ssh_key = "ssh public key" # use for create key-pair
+cluster_name = "cluster name"
+vms_image_id = "image id"
+vms_ssh_key = "ssh public key" # use for create key-pair
 
-TF_VAR_master_count = "master nodes count" # default = "1"
-TF_VAR_master_flavor_id = "master flavor id"
+master_count = "master nodes count" # default = "1"
+master_flavor_id = "master flavor id"
 
-TF_VAR_workers_count = "worker nodes count"
-TF_VAR_worker_flavor_id = "worker flavor id"
+workers_count = "worker nodes count"
+worker_flavor_id = "worker flavor id"
 ```
 ## For HA scheme use parameters
 ```bash
-TF_VAR_cluster_VIP = "true" # default = false
-TF_VAR_master_count = "3"   # default = 1
+cluster_VIP = "true" # default = false
+master_count = "3"   # default = 1
 ```
 ## This module returns
 ```bash
