 You can also perform different authentication methods like sourcing your `.ostackrc` file or using the OpenStack `clouds.yaml` file.  
 For more information have a look in the [os_server](https://docs.ansible.com/ansible/latest/modules/os_server_module.html) Ansible module documentation.

-  - Password for the user `linux` (**you should definitely change that**)  
-    You may have to adjust the `remote_user` in the Ansible Playbooks under [ansible](ansible) if you are using a normal/default Debian base image
-  - (Optional) For using a custom `ews.cfg` set to `true`; See here: [Optional: Custom `ews.cfg`](#ews-cfg)

+## Ansible remote user
+You may have to adjust the `remote_user` in the Ansible Playbook under [`openstack/deploy_tpot.yaml`](openstack/deploy_tpot.yaml) depending on your Debian base image (e.g. on Open Telekom Cloud the default Debian user is `linux`).

+## Instance settings
+Located at [`openstack/roles/deploy/vars/main.yaml`](openstack/roles/deploy/vars/main.yaml).  
+Here you can customize your virtual machine specifications:
+  - Specify the region name
+  - Choose an availibility zone. For Open Telekom Cloud reference see [here](https://docs.otc.t-systems.com/en-us/endpoint/index.html).
+  - Change the OS image (For T-Pot we need Debian 9)
+  - (Optional) Change the volume size
+  - Specify your key pair
+  - (Optional) Change the instance type (flavor)  
     `s2.medium.8` corresponds to 1 vCPU and 8GB of RAM and is the minimum required flavor.  
-    A full list of flavors can be found [here](https://docs.otc.t-systems.com/en-us/usermanual/ecs/en-us_topic_0035470096.html).
-  - Change the OS (Don't touch; for T-Pot we need Debian 9)
-  - Specify the VPC, Subnet, Security Group and Key Pair you created before
-  - (Optional) Change the disk size
-  - You can choose from multiple Availibility Zones (AZ). For reference see [here](https://docs.otc.t-systems.com/en-us/endpoint/index.html).
