+# cloudflare-ddns-update - Dyn v3 API that manages DNS entries in cloudflare
+
+## Introduction
+
+The [Dyn v3 API](https://help.dyn.com/remote-access-api/perform-update/) to update dynamic DNS records is used in 
+multiple routers on the market. This tool allows to provide this API while managing the dynamic DNS records in cloudflare.
+
+## Configuration
+
+The tool requires the following environment variables to be set:
+
+* CLOUDFLARE_API_TOKEN: The API token used to authenticate against the cloudflare API
+* CLOUDFLARE_ZONE: The name of the DNS zone to manage
+* AUTH_USERNAME: A username that is required to be used for the Dyn API
+* AUTH_PASSWORD: A password that is required to be used for the Dyn API
+
+Optionally, DEBUG can be set to anything to enable logging of cloudflare requests and responses.
+
+## Usage
+
+After setting the environment variables, simply run the tool
+
+    ./cloudflare-ddns-update
+
+## Container image / Docker
+
+This is also available as a container image, e.g. via Docker:
+
+    docker run -e CLOUDFLARE_API_TOKEN=secret -e CLOUDFLARE_ZONE=example.com -e AUTH_USERNAME=testuser -e AUTH_PASSWORD=secret ghcr.io/dploeger/cloudflare-ddns-update:latest
+
+## Helm chart
