+# Automated Gmail sender
+
+## Key features
+- Secure SMTP connection using TLS
+- Support for attachments
+- Error handling
+- Easy to integrate into other Python programs
+- Object-oriented design for re-usability
+
+## Setup instructions
+
+To use this script, you'll need to follow these steps:
+
+1. First, set up Google App Password:
+- Go to your Google Account settings
+- Navigate to Security > 2-Step Verification
+- At the bottom, click on "App passwords"
+- Generate a new app password for your Python script
+- Save this password safely (you'll only see it once)
+
+Note:
+In https://myaccount.google.com/security, do you see 2-step verification set to ON? If yes, then visiting https://myaccount.google.com/apppasswords should allow you to set up application specific passwords. 
+
+2. Install "secure-smtplib"
+```
+pip install secure-smtplib
+```
+
+Use the script
+```
+# Create the sender object
+sender = GmailSender("[email protected]", "your-app-password")
+
+sender.send_email(
+    to_email="[email protected]",
+    subject="Hello!",
+    body="This is an automated email."
+)
+
+# Use the below script to send the email via attachments
+sender.send_email(
+    to_email="[email protected]",
+    subject="Report",
+    body="Please find the attached report.",
+    attachments=["report.pdf", "data.xlsx"]
+)
+```
+
+## Author
+Mihir Deshpande
+
+## Important security notes:
+- Never share your app password
+- Don't commit the script with your credentials
+- Consider using environment variables for sensitive data
