+# Mullvad Account Expiry Notifier
+
+## # Features
+
+* Reads 16-digit account numbers from a file (accounts.txt).
+* Fetches expiration dates from the Mullvad API.
+* Sends alerts to a specified Discord webhook if an account is nearing expiration.
+* Ensures valid account numbers and handles API response errors gracefully.
+
+### Prerequisites
+
+- A valid accounts.txt file containing Mullvad account numbers (one per line).
+- A Discord webhook URL for notifications.
+- Required dependencies: curl, jq, and date.
+
+### Installation
+
+Ensure the script has execution permissions:
+
+```
+chmod +x check_mullvad_account_expiry.sh
+
+```
+### Usage
+
+Create a file named accounts.txt and list Mullvad account numbers:
+
+```
+1234567890123456
+9876543210987654
+```
+
+Set your Discord webhook URL in the script:
+
+```
+DISCORD_WEBHOOK_URL="your_discord_webhook_url"
+```
+
+Run the script:
+
+```
+./check_mullvad_account_expiry.sh
+```
+
+### Configuration
+
+- TXT_FILE: The file containing Mullvad account numbers (default: accounts.txt).
+
+- DAYS_THRESHOLD: Number of days before expiry to trigger an alert (default: 14).
+
+- DISCORD_WEBHOOK_URL: The webhook URL to send alerts to Discord.
+
+#### Example Output
+
+Account 1234567890123456 expires in 10 days.
+Sending Discord notification...
+Account 9876543210987654 expires in 20 days.
+
+### Notes
+
+Ensure the accounts.txt file contains only valid 16-digit Mullvad account numbers.
+The script adds a small delay between API requests to prevent rate-limiting.
+Modify DAYS_THRESHOLD to adjust the notification period.
