+Mailing List Etiquette
+======================
+
+[[introduction]]
+== Introduction
+
+Open source, community projects such as Git use a mailing list and email to
+coordinate development and to submit patches for review. This article documents
+the unspoken rules and etiquette for the proper way to send email to the
+mailing list. What follows are considered best practices to follow.
+
+If you are looking for details on how to submit a patch, that is documented
+elsewhere in:
+
+- `Documentation/SubmittingPatches`
+- `Documentation/MyFirstContribution.txt`
+
+[[proper-use-of-to-and-cc]]
+== Proper Use of To and Cc
+
+When starting a new email thread that is not directed at any specific person,
+put the mailing list address in the "To:" field, otherwise address it to the
+person and put the mailing list address in the "Cc:" field.
+
+When replying to an email on the mailing list, put the person you are replying
+to in the "To:" field and all other people in the thread in the "Cc:" field,
+including the mailing list address.
+
+Make sure to keep everyone involved in the "Cc:" field so that they do not have
+to be subscribed to the mailing list to receive replies.
+
+[[do-not-use-mail-followup-to]]
+== Do Not Use Mail-Followup-To
+
+When posting to the mailing list, your email client might add a
+"Mail-Followup-To:" field which contains all of the recipients, including the
+mailing list address, but not the sender's email address. This is intended to
+prevent the sender from receiving replies twice, once from the replying person
+and again from the mailing list.
+
+This goes directly against the desired "To:" and "Cc:" etiquette (see "Proper
+Use of To and Cc" above). Most users want to use "group reply" or "Reply to
+all" in their mail client and create a reply email that is sent directly to
+author of the email they are replying to with all other recipients, as well as
+the mailing list address, in the "Cc:" field.
+
+The proper thing to do is to never use the "Mail-Followup-To:" field as well as
+disable honoring any "Mail-Followup-To:" fields in any emails you reply to.
+Some email clients come with both enabled by default. Mutt is like this (see
+Disable Mail-Followup-To in the Mutt section below).
+
+[[enable-plain-text-mode]]
+== Enable Plain Text Mode
+
+Most email clients automatically reject mailing list email if it is not a
+text/plain formatted email. For that reason, it is important that your email
+client is set to create text/plain emails instead of text/enriched or
+text/html email.
+
+[[patches-that-receive-no-response]]
+
+From Junio's notes from the maintainer:
+
+> If you sent a patch and you did not hear any response from anybody for
+> several days, it could be that your patch was totally uninteresting,
+> but it also is possible that it was simply lost in the noise.  Please
+> do not hesitate to send a reminder message in such a case.  Messages
+> getting lost in the noise may be a sign that those who can evaluate
+> your patch don't have enough mental/time bandwidth to process them
+> right at the moment, and it often helps to wait until the list traffic
+> becomes calmer before sending such a reminder.
+
+[[send-merge-ready-patches-to-the-maintainer]]
+== Send Merge-Ready Patches to the Maintainer
+
+Once a patch has achieved consensus and all stakeholders are staisfied and
+everything is ready for merging, then you send it to the maintainer: "To:
+gitster@pobox.com".
+
+[[mutt-config]]
+== Mutt Config
+
+This section has suggestions for how to set up Mutt to be polite.
+
+[[known-mailing-lists]]
+=== Known Mailing Lists
+
+Mutt has the ability to change its behavior when replying to a mailing list. For
+Mutt to know when an address is a mailing list, use the `subscribe` keyword in
+your Mutt configuration:
+
+**~/.muttrc:**
+```
+# tell Mutt about the Git mailing list
+subscribe git@vger.kernel.org
+```
+
+[[reply-properly]]
+=== Reply Properly
+
+By default, Mutt uses the 'g' and 'L' hotkeys to execute a "group reply" or
+"list reply" respectively. A "group reply" creates an email addressed to the
+sender with all other recipients in the "Cc". A "list reply" starts an email
+addressed only to the mailing list without anybody else as "Cc".
+
+Per rule X, Y, and Z above, using "group reply" in Mutt is what you want to do.
+
+[[disable-mail-followup-to]]
+=== Disable Mail-Followup-To
+
+By default, when replying to mailing lists, Mutt will automatically generate
+"Mail-Followup-To" headers. To fix this, disable the generation of the header
+in your Mutt configuration. It is also a good idea to disable honoring any
+"Mail-Followup-To" headers so that any "group reply" operations are correctly
+addressed.
+
+**~/.muttrc:**
+```
+# disable Mail-Followup-To header
+unset followup_to
+
+# disable honoring Mail-Followup-To header
+unset honor_followup_to
+```
+
