-## Overview of this repository
-
-This repository drives the development of "chatmail instances",
-comprised of minimal setups of
-
-- [postfix smtp server](https://www.postfix.org)
-- [dovecot imap server](https://www.dovecot.org)
-
-as well as custom services that are integrated with these two:
-
-- `chatmaild/src/chatmaild/doveauth.py` implements
-  create-on-login account creation semantics and is used
-  by Dovecot during login authentication and by Postfix
-  which in turn uses [Dovecot SASL](https://doc.dovecot.org/configuration_manual/authentication/dict/#complete-example-for-authenticating-via-a-unix-socket)
-  to authenticate users
-  to send mails for them.
-
-- `chatmaild/src/chatmaild/filtermail.py` prevents
-  unencrypted e-mail from leaving the chatmail instance
-  and is integrated into postfix's outbound mail pipelines.
-
-There is also the `cmdeploy/src/cmdeploy/cmdeploy.py` command line tool
-which helps with setting up and managing the chatmail service.
-`cmdeploy run` uses [pyinfra-based scripting](https://pyinfra.com/)
-in `cmdeploy/src/cmdeploy/__init__.py`
-to automatically install all chatmail components on a server.
+- Starts a browser window automatically where you can "refresh" as needed.

-## Emergency Commands to disable automatic account creation
-
-If you need to stop account creation,
-e.g. because some script is wildly creating accounts,
-login to the server with ssh and run:
-
-```
-    touch /etc/chatmail-nocreate
-```
-
-While this file is present, account creation will be blocked.
-
 ### Ports
 
 Postfix listens on ports 25 (smtp) and 587 (submission) and 465 (submissions).
 Dovecot listens on ports 143(imap) and 993 (imaps).
 
-Delta Chat apps will, however, discover all ports and configurations
-automatically by reading the `autoconfig.xml` file from the chatmail service.
