+# Cloudflare DNS Records
+
+## Description
+
+This Ansible role automates the management of DNS A-records in Cloudflare zones. It uses the [community.general.cloudflare_dns](https://docs.ansible.com/ansible/latest/collections/community/general/cloudflare_dns_module.html) module to create or update A-records for a list of domains, automatically detects the correct zone for each record, and supports configurable proxy settings.
+
+## Overview
+
+Looping over a provided list of domains (`cloudflare_domains`), this role:
+- Determines the zone name by extracting the last two labels of each domain.
+- Ensures an A-record for each domain points to the specified IP (`cloudflare_target_ip`).
+- Honors the `proxied` flag to switch between DNS-only and Cloudflare-proxied modes.
+- Provides an optional debug task (`enable_debug`) to output the domain list before changes.
+
+Ideal for environments where bulk or dynamic DNS updates are needed, this role abstracts away the complexity of Cloudflare’s zone and record API.
+
+## Purpose
+
+Cloudflare DNS Records delivers an idempotent, scalable solution for managing A-records across multiple Cloudflare zones. Whether you need to onboard hundreds of domains or toggle proxy settings in CI/CD pipelines, this role handles the orchestration and ensures consistency.
+
+## Features
+
+- **Automatic Zone Detection:** Parses each domain to derive its zone (`example.com`) without manual intervention.  
+- **Bulk Record Management:** Creates or updates A-records for all entries in `cloudflare_domains`.  
+- **Proxy Toggle:** Configure `proxied: true` or `false` per record to switch between DNS-only and proxied modes.  
+- **Debug Support:** Enable `enable_debug` to print the domain list for validation before execution.  
+- **Flexible Authentication:** Supports both API token (`api_token`) and Global API key + email.  
+- **Low-TTL Option:** Use `ttl: 1` for rapid DNS propagation during dynamic updates.
