 # Cloudflare DNS Updater
 
-## Create and activating a venv
 
-Make sure Python 3.10 or higher is installed.
-Use `cd` to change to the location of this repository.
 
-Now, run
-```
-py -3.10 -m venv venv
-```
-Replace the `-3.10` with other Python versions if necessary (ex.: `-3.11`)
+## Using the application
 
-Activate the venv using the command
-```
-venv/scripts/activate
+The application necessarily requires a valid Cloudflare API Token.
+Further the application must be located in the same network as the configured zones.
+
+| Environment Variable | Required |               Usage                |
+|:--------------------:|:--------:|:----------------------------------:|
+|     CF_API_TOKEN     |    x     |        Cloudflare API Token        |
+|   STATUS_POST_URL    |          | Post Endpoint for a Uptime Monitor |
+*Note: Variables can be stored in a .env file*
+
+The actual configuration happens in two or more files:  
+`interfaces.toml` contains all IPv6 interfaces available/used by the zone config files.  
+`.toml` files in `zone.d` contain settings for individual zones.
+
+Example:
+
+*interfaces.toml*
+```toml
+[[interface]]
+alias = "example-interface-1"     # this is what a user inputs in the zone.toml
+address = ":da5e:d3ff:feeb:4346"  # static part of the IP, the rest will be dynamically generated using the host
 ```
 
-## Installing the required packages
+*zone.d/example.org.toml*
+```toml
+email = "owner@example.org"             # Email of User owning the Zone
+name = "example.org"                    # Zone Name
+id = "0183f167a051f1e432c0d931478638b5" # Zone ID
 
-Make sure the venv is activated.
-
-Run the following command
-```
-pip install -r requirements.txt
+[[entry]]
+name="example.org"              # "@" Symbol is not currently supported 
+type="10"                       # Options are: "4" (only IPv4/A Record), "6" (only IPv6/AAAA Record) and "10" (both)
+interface="example-interface-1" # Only required on type values 6 and 10
 ```
 
-Alternatively, the packages can be installed manually by using `pip install`.
-
-The full list of packages needed:
-- cloudflare (Version 2.0.0 or greater)
-- Buildins:
-  - json
-  - configparser
-  - ipaddress
-  - sys
-
-## Using the script
-
-Before running the script, make sure there exists a `config.ini` file next to the `cloudflare_script.py`.
-The config has to have the following structure:
-```ini
-[cloudflare]
-TOKEN=<cloudflare api token>
-
-[server]
-HOSTNAME=hostname-of-website.com
-```
-
-Run the script using the following arguments:
-```
-python cloudflare_script.py <ipversion> <path/to/ip/list>
-```
-
-IP-Version can be 4 or 6.
-The IP-List has to conform to the following structure and be a json file:
-```json
-{
-  "AAAA": [
-    "ipv6 site prefix"
-  ],
-  "A": [
-    "ipv4 site prefix"
-  ]
-}
-```
-
-To only get the currently registered DNS records for a given API key, run
-```
-python cloudflare_script.py
-```
-THis will print all DNS records for the API key with name, ip, cloudflare id and ip-version
