+    important notes about using gmail
+
+    - Gmail has locked things down pretty good with what it considers less secure apps. That 
+        would include access your Gmail account from the smtplib library in Python. However, there 
+        is a work around. You can enable access from "Less Secure Apps" by going to your Gmail 
+        account and enabling that feature. However, you should do this at your own peril, and after 
+        carefully reading the warnings: https://support.google.com/accounts/answer/6010255.
