 ## Config
 
 Configuration can be done through env variables or programmatically through the `Config` object
 The following env variables are supported:
 
 ```bash
-VAULT_ADDR				Vault server URL (default http://localhost:8200)
-VAULT_CAPATH			CA path
-VAULT_TOKEN				Vault Token
-VAULT_ROLEID			Vault app role id
-VAULT_SECRETID			Vault app role secret id
-VAULT_CLIENT_TIMEOUT	Client timeout
-VAULT_SKIP_VERIFY		Do not check SSL
