+Delete all the DNS records in a domain in Cloudflare.
+
+This program will delete all the DNS records in a given domain. Before deletion, it'll also take a backup of the existing DNS records and save it as a .txt file in [BIND](https://www.isc.org/bind/) format.
+
+## Prerequisites
+- [Python 3](https://www.python.org/)
+- Pip
+
+    >sudo apt install python3-pip
+
+- [Python requests library](https://pypi.org/project/requests/)
+
+    >pip install requests
+
+- CloudFlare API key
+
+    You need a CloudFlare API key with access to *edit zone DNS* access for the domain:
+
+    1. Go to your Cloudflare profile and then [API Tokens](https://dash.cloudflare.com/profile/api-tokens)
+    2. Click on *Create Token*
+    3. You can use the template *Edit Zone DNS*
+    4. Enter the of the domain(s) you want to delete DNS from in *Zone Resources*
+    5. Click *Continue to summary* and the *Create Token*
+    6. You should get an API Token now.
+
+
+## Running the program
+
+1. Download and extract the zip file or Clone this repository:
+
+    >git clone https://git.pavakpaul.com/pavak/cloudflare-delete-all-dns-records.git
+
+2. cd to the directory:
+
+    >cd 
+cloudflare-delete-all-dns-records
+
+3. Run app.py using python3 and follow the instructions
+
+    >python3 app.py
+
+### Using a config file to pass the API credentials
+
+If you want to delete all the DNS records from multiple domains, it is a good idea to use a single token for mutiple domains. In that case, you can use save your credentials in config.json. Simply rename config_sample.json to config.json: `mv config_sample.json config.json` and save your configuration there. To load the config file, simply pass the argument _loadconfig_:
+
+>python3 app.py loadconfig
+
+You still can't delete DNS from multiple domains to reduce accidental removals of DNS. To be safe, it's always a good idea to just create a token for a single domain.
