 ExternalDNS serves as an add-on for Kubernetes designed to automate the management of Domain Name System (DNS)
 records for Kubernetes services by utilizing various DNS providers. While Kubernetes traditionally manages DNS
 records internally, ExternalDNS augments this functionality by transferring the responsibility of DNS records
-management to an external DNS provider such as STACKIT. Consequently, the STACKIT webhook enables the management
-of your STACKIT domains within your Kubernetes cluster using
+management to an external DNS provider such as Selectel. Consequently, the Selectel webhook enables the management
+of your Selectel domains within your Kubernetes cluster using
 [ExternalDNS](https://github.com/kubernetes-sigs/external-dns).
 
-For utilizing ExternalDNS with STACKIT, it is mandatory to establish a STACKIT project, a service account
-within the project, generate an authentication token for the service account, authorize the service account
-to create and read dns zones, and finally, establish a STACKIT zone.
+For utilizing ExternalDNS with Selectel, it is mandatory to establish a Selectel project, a service account
+within the project, and finally, establish a Selectel zone.
 
 ## Kubernetes Deployment
 
-The STACKIT webhook is presented as a standard Open Container Initiative (OCI) image released in the
-[GitHub container registry](https://github.com/stackitcloud/external-dns-stackit-webhook/pkgs/container/external-dns-stackit-webhook).

 The deployment is compatible with all Kubernetes-supported methods. The subsequent example
 demonstrates the deployment as a
 [sidecar container](https://kubernetes.io/docs/concepts/workloads/pods/#workload-resources-for-managing-pods)
 within the ExternalDNS pod.

-- `--project-id`/`PROJECT_ID` (required): Specifies the project id of the STACKIT project.
-- `--auth-token`/`AUTH_TOKEN` (required if `auth-key-path` is not set): Defines the authentication token for the STACKIT API. Mutually exclusive with 'auth-key-path'.
-- `--auth-key-path`/`AUTH_KEY_PATH` (required if `auth-token` is not set): Defines the file path of the service account key for the STACKIT API. Mutually exclusive with 'auth-token'.

+- `--password`/`PASSWORD` (required): Specifies the password of your service user to authorize.
 - `--worker`/`WORKER`  (optional): Specifies the number of workers to employ for querying the API. Given that we
   need to iterate over all zones and records, it can be parallelized. However, it is important to avoid
   setting this number excessively high to prevent receiving 429 rate limiting from the API (default 10).

-## FAQ
-
-### 1. Issue with Creating Service using External DNS Annotation
-
-If your zone is `example.runs.onstackit.cloud` and you're trying to create a service with the following external DNS
-annotation:
-
-    ```yaml
-    apiVersion: v1
-    kind: Service
-    metadata:
-      annotations:
-        external-dns.alpha.kubernetes.io/hostname: example.runs.onstackit.cloud
-      labels:
-        app.kubernetes.io/name: ingress-nginx
-        app.kubernetes.io/instance: nginx
-        app.kubernetes.io/part-of: ingress-nginx
-        app.kubernetes.io/component: controller
-      name: nginx-ingress-controller
-      namespace: nginx-ingress-controller
-    spec:
-      type: LoadBalancer
-      externalTrafficPolicy: Local
-      ipFamilyPolicy: SingleStack
-      ipFamilies:
-        - IPv4
-      ports:
-        - name: http
-          port: 80
-          protocol: TCP
-          targetPort: http
-        - name: https
-          port: 443
-          protocol: TCP
-          targetPort: https
-      selector:
-        app.kubernetes.io/component: controller
-        app.kubernetes.io/instance: nginx
-        app.kubernetes.io/name: ingress-nginx
-    ```
-
-<b>Why isn't it working?</b>
-
-<b>Answer</b>: The External DNS will try to create a TXT record named `a-example.runs.onstackit.cloud`, which will fail
-because you can't establish a record outside the zone. The solution is to use a name that's within the zone, such as
-`nginx.example.runs.onstackit.cloud`.
-
-### 2. Issues with Creating Ingresses not in the Zone
-
-For a project containing the zone `example.runs.onstackit.cloud`, suppose you've created these two ingress:
-
-    ```yaml
-    apiVersion: networking.k8s.io/v1
-    kind: Ingress
-    metadata:
-      annotations:
-        ingress.kubernetes.io/rewrite-target: /
-        kubernetes.io/ingress.class: nginx
-      name: example-ingress-external-dns
-      namespace: default
-    spec:
-      rules:
-        - host: test.example.runs.onstackit.cloud
-          http:
-            paths:
-              - backend:
-                  service:
-                    name: example
-                    port:
-                      number: 80
-                path: /
-                pathType: Prefix
-        - host: test.example.stackit.rocks
-          http:
-            paths:
-              - backend:
-                  service:
-                    name: example
-                    port:
-                      number: 80
-                path: /
-                pathType: Prefix
-    ```
-
-<b>Why isn't it working?</b>
-
-<b>Answer</b>: External DNS will attempt to establish a record set for `test.example.stackit.rocks`. As the zone
-`example.stackit.rocks` isn't within the project, it'll fail. There are two potential fixes:
-
-- Incorporate the zone `example.stackit.rocks` into the project.
-- Adjust the domain filter to `example.runs.onstackit.cloud` by setting the domain filter
-  flag `--domain-filter="example.runs.onstackit.cloud"`. This will exclude `test.example.stackit.rocks` and only
-  generate
-  the record set for `test.example.runs.onstackit.cloud`.
-
 ## Development
 
 Run the app:
 
 ```bash
-export BASE_URL="https://dns.api.stackit.cloud"
 export PROJECT_ID="c158c736-0300-4044-95c4-b7d404279b35"
-export AUTH_TOKEN="your-auth-token"
+export ACCOUNT_ID="123456"
+export USERNAME="username"
+export PASSWORD ="password"
 
 make run
 ```
