 # realDynDNS
-
 RealDynDNS aims to be a replacement to "classical" dynDNS solutions that offer a subdomain. Instead realDynDns actually changes your DNS entries.

 This service requires your DNS provider to expose an API that allows your DNS entries to be changed.
 A service that provides your current external IP is also required.

 ## Configuration
-
 The configuration is done via a YAML file called `config.yaml`. The following example shows the configuration for a domain with two subdomains.

 Configuration of the IP provider and the DNS provider is mandatory.

 ```

 The config file is expected to be in the same directory as the binary and called `config.yaml`. For the OCR image, the root directory is `/app`.

 ## DNS Providers
-
 The DNS provider abstracts the API of your DNS provider. Currently the following providers are supported:

 ### IONOS
-
 IONOS requires two configuration parameters. You can get your API key [here](https://developer.hosting.ionos.com/docs/getstarted).
-
 ```yaml
 api_key: <your-api-key>
 base_url: https://api.hosting.ionos.com/dns
 ```

 ## External IP Providers
-
 The external IP provider is used to get your current external IP. Currently the following providers are supported:

 ### Plain
-
 Any provider that returns your IP as plain text can be used. The following configuration is required:
-
 ```yaml
 url: <your-providers-URL>
 ```

 Examples for providers are:
-
 - https://ifconfig.me
 - https://api.ipify.org

 ## Notification Providers
-
 The notification provider is used to send notifications whena IP address changes and a DNS record is updated.

 ### Console
-
 The console notification provider is used to print the notification to the console. This is the default notification provider.

 ### Gotify
-
 The Gotify notification provider is used to send notifications to a Gotify server.

 The priority must be between 0 and 4.

-## Mode Selection
-
-Two modes are available:
-
-### RunOnce
-
-The RunOnce mode is used to run the application once and exit. This is useful when providing your own external scheduler, like cron.
-
-Set the `mode` to `RunOnce`.
-
-### Scheduled
-
-The Scheduled mode is used to run the application in a scheduled interval.
-
-Set the `mode` to `Scheduled` and provide a cron expression for the `check_interval`.
