+==========================
+Drag & drop emails to Odoo
+==========================
+
+This module was written to allow users to drag&drop emails from their desktop to Odoo.
+
+It supports as well RFC822 .eml files as Outlook .msg (those only if `an extra library <https://github.com/mattgwwalker/msg-extractor>`_ is installed) files.
+
+Usage
+=====
+
+To use this module, you need to:
+
+#. save your emails on the desktop / somewhere in the file system
+#. drag them to your browser, and drop them on the chatter of the record you want to attach your email to

+
+Known issues / Roadmap
+======================
+
+* most mail clients won't allow you to drag mails directly from the mail client, you'll need some plugin for that
+* for corporate environments, it might be feasible to support imap URLs and get the mail in question on the server side
