+This project is unmaintained
+============================
+
+This project is officially marked as unmaintained, since my life is somewhere where I just do not have the time and energy to lead this project.
+
+If there is someone out there willing to take the lead, please get in contact, but even if there is, I can't get in contact with the original author `@carpedm20 <https://github.com/carpedm20>`__ and get the ability to add others as maintainers, see `issue 390 <https://github.com/carpedm20/fbchat/issues/390>`__. So a fork might be preferable.
+
+I have opened for further discussion `in issue 613 <https://github.com/carpedm20/fbchat/issues/613>`__.
+
+Thanks for serving you all these years.
