+## Gmail configuration
+
+**NOTE**: This section explains how to reconfigure a gmail account that
+is _already_ configured to use a torproject.org address.  If you need to add
+a new address from scratch, the process will be a little different.
+
+1. Click  on "Settings".  (That  should be the  big gear icon  towards thetop
+right of your window.)
+
+2. A "quick settings" menu should open.  Click on the "See all settings"
+button at the top of that menu.
+
+3. This will take you to a "Settings" page. Click on the "Accounts and
+Import" tab at the top of the page.
+
+4. Under "Send mail as", find the address for <yourname@torproject.org>, and
+lick the "edit info" link to the right of that account. (If the address isn't
+there, then your gmail account isn't set up to use your TPO account. You'll
+need to click "Add another email address" instead, and the process below will
+be slightly different.)
+
+5. A new "Edit email address" popup should open.  Click "Next step" on it.
+
+6. Finally, you'll be at a window that says "Edit email address".  Fill it
+out like this:
+
+ - Select "Send through torproject.org SMTP servers".
+ - Set "SMTP Server:" to "submission.torproject.org"
+ - Set "Port:" to 587.
+ - Set "Username:" to your username (_without_ "@torproject.org").
+ - Set "Password:" to the email submission password that you configured.
+ - Select "Use TLS", not "Use SSL".
+
+Double-check everything, then click "Save Changes".  Gmail will try
+authenticating to the SMTP server; if it's successful, then the popup window
+will close and your account will be updated.
