 # terraform-vault
 
-A repository to manage the configuration of Vault secret engines, authentication modes and policies.
+A repository to manage the configuration of Vault secret engines, authentication modes and policies.
+
+
+# Usage
+
+1. Initialize Terraform
+
+Once you have your backend block configured, you need to initialize your Terraform working directory to configure the backend:
+
+```bash
+terraform init
+```
+
+This command initializes the backend and checks the connection to Consul. If everything is set up correctly, Terraform will start using Consul as its backend for storing the state.
+
+2. Common terraform init Errors
+
+If you encounter errors while running terraform init, check the following:
+
+    Consul server is reachable: Make sure that the address is correct and that you can connect to the Consul server.
+    Consul token (if using ACLs): Verify that the token has the correct permissions to write to the specified path in the Consul KV store.
+
+3. Example Consul KV Structure
+
+In Consul, the state file will be stored in the KV store under the specified path:
+
+```bash
+terraform/state
+```
+
+You can check the Consul KV store by accessing the Consul UI or using the consul kv command to see the stored Terraform state:
+
+```bash
+consul kv get terraform/state
+```
