+4. Notes for running OpenSlides in larger setups
-======================
+------------------------------------------------
 
-To install OpenSlides for big assemblies (in 'big mode') you have to setup some
+For productive setups refer to the docker-compose setup described in the main
-additional components and configurations. In the 'big mode' you should use a webserver
+`README<https://github.com/OpenSlides/OpenSlides/blob/master/README.rst>`_.
-like NGINX to serve the static and media files as proxy server in front of your OpenSlides
-interface server. You should also use a database like PostgreSQL. Use Redis as channels backend,
-cache backend and session engine. Finally you should use gunicorn with uvicorn as interface server.
 
+While develpment it might be handy to use a cache and another database.
+PostgreSQL is recommended and Redis necessary as a cache. Both can be set up in
+the ``settings.py``. Please consider reading the `OpenSlides configuration
+<https://github.com/OpenSlides/OpenSlides/blob/master/server/SETTINGS.rst>`_ page
+to find out about all configurations, especially when using OpenSlides for big
+assemblies.
 
-1. Install and configure PostgreSQL and Redis
+If you followed the instructions and installed the pip requirements form the
----------------------------------------------
+``requirements.py`` all needed dependencies for another worker are installed.
-
+Instead of running ``python manage.py runserver`` you can use daphne or gunicorn
-Install `PostgreSQL <https://www.postgresql.org/>`_ and `Redis
+(the latter is used in the prod setup)::
-<https://redis.io/>`_. For Ubuntu 18.04 e. g. run::
-
-    $ sudo apt-get install postgresql libpq-dev redis-server
-
-Be sure that database and redis server is running. For Ubuntu 18.04 e. g. this
-was done automatically if you used the package manager.
-
-Then add database user and database. For Ubuntu 18.04 e. g. run::

-
+instructions
-1. Installation on GNU/Linux or Mac OS X
-----------------------------------------
-
-a. Check requirements
-'''''''''''''''''''''
-
-Make sure that you have installed `Python (>= 3.6) <https://www.python.org/>`_
-on your system.
-
-Additional you need build-essential packages, header files and a static
-library for Python and also the pyvenv-3 binary package for python3.
-
-E.g. run on Debian/Ubuntu::
-
-    $ sudo apt-get install build-essential python3-dev python3-venv
-
-
-b. Setup a virtual Python environment (optional)
-''''''''''''''''''''''''''''''''''''''''''''''''
-
-You can setup a virtual Python environment using the virtual environment
-(venv) package for Python to install OpenSlides as non-root user.
-
-Create your OpenSlides directory and change to it::
-
-    $ mkdir OpenSlides
-    $ cd OpenSlides
-
-Setup and activate the virtual environment::
-
-    $ python3 -m venv .virtualenv
-    $ source .virtualenv/bin/activate
-    $ pip install --upgrade setuptools pip
-
-
-c. Install OpenSlides
-'''''''''''''''''''''
-
-To install OpenSlides just run::
-
-    $ pip install openslides
-
-This installs the latest stable version. To install a specific (beta)
-version use ``openslides==x.y``.
-
-You can also use the package from the `OpenSlides website
-<https://openslides.com/>`_. Download latest OpenSlides release as
-compressed tar archive and run::
-
-    $ pip install openslides-x.y.tar.gz
-
-This will install all required Python packages (see
-``requirements/production.txt``).
-
-
-d. Start OpenSlides
-'''''''''''''''''''
-
-To start OpenSlides simply run::
-
-    $ openslides
-
-If you run this command the first time, a new database and the admin account
-(Username: ``admin``, Password: ``admin``) will be created. Please change the
-password after first login!
-
-OpenSlides will start a webserver. It will also try to open the webinterface in
-your default webbrowser. The server will try to listen on the local ip address
-on port 8000. That means that the server will be available to everyone on your
-local network (at least for commonly used network configurations).
-
-If you use a virtual environment (see step b.), do not forget to activate
-the environment before restart after you closed the terminal::
-
-    $ source .virtualenv/bin/activate
-
-To get help on the command line options run::
-
-    $ openslides --help
-
-You can store settings, database and other personal files in a local
-subdirectory and use these files e. g. if you want to run multiple
-instances of OpenSlides::
-
-    $ openslides start --local-installation
-
-
-2. Installation on Windows
---------------------------
-
-Follow the instructions above (1. Installation on GNU/Linux or Mac OS X) but care
-of the following variations.
-
-To get Python download and run the latest `Python 3.7 32-bit (x86) executable
-installer <https://www.python.org/downloads/windows/>`_. Note that the 32-bit
-installer is required even on a 64-bit Windows system. If you use the 64-bit
-installer, step 1c of the instruction might fail unless you installed some
-packages manually.
-
-In some cases you have to install `MS Visual C++ 2015 build tools
-<https://www.microsoft.com/en-us/download/details.aspx?id=48159>`_ before you
-install the required python packages for OpenSlides (unfortunately Twisted
-needs it).
-
-To setup and activate the virtual environment in step 1b use::
-
-    > .virtualenv\Scripts\activate.bat
-
-All other commands are the same as for GNU/Linux and Mac OS X.
-
-
-3. Installation with Docker
----------------------------
-
-The installation instruction for (1) and (2) described a way to use OpenSlides in a
-'small mode' with max 10 concurrent clients. To install OpenSlides for big assemblies
-('big mode') you have to setup some additional components and configurations.
-
-The easiest way to run the OpenSlides 'big mode' environment (with PostgreSQL, Redis
-and NGINX) with Docker Compose: use our docker compose suite. Follow the instruction in
-the `openslides-docker-compose Repository <https://github.com/OpenSlides/openslides-docker-compose>`_.
-
-To install and configure all components of our 'big mode' manually you can read the
-`big-mode-instruction <https://github.com/OpenSlides/OpenSlides/blob/master/DEVELOPMENT.rst#openslides-in-big-mode>`_
-
-
-Configuration
-=============
-
-Please consider reading the `OpenSlides configuration
-<https://github.com/OpenSlides/OpenSlides/blob/master/SETTINGS.rst>`_ page to
-find out about all configurations, especially when using OpenSlides for big
-assemblies.
-
-

-
-To setup a development environment for OpenSlides follow the instruction of
-`DEVELOPMENT.rst
 <https://github.com/OpenSlides/OpenSlides/blob/master/DEVELOPMENT.rst>`_.
 
+Note: This is temporary and will be replace with nice scripts...
+
+First, you have to clone this repository::
+
+    $ git clone https://github.com/OpenSlides/OpenSlides.git
+    $ cd OpenSlides/docker/
+
+You need to build the Docker images for the client and server with this
+script::
+
+    $ ./build.sh all
+
+You must define a Django secret key in ``secrets/django.env``, for example::
+
+    $ printf "DJANGO_SECRET_KEY='%s'\n" \
+      "$(tr -dc 'a-zA-Z0-9' < /dev/urandom | head -c 64)" > secrets/django.env
+
+We also strongly recommend that you set a secure admin password but it is not
+strictly required.  If you do not set an admin password, the default login
+credentials will be displayed on the login page.  Setting the admin password::
+
+    $ cp secrets/admin.env.example secrets/admin.env
+    $ vi secrets/admin.env
+
+Afterwards, generate the configuration file::
+
+    EXTERNAL_HTTP_PORT=8000 m4 docker-compose.yml.m4 > docker-compose.yml
+
+Finally, you can start the instance using ``docker-compose``::
+
+    $ docker-compose up
+    $ # or:
+    $ docker-compose up -d
+    $ docker-compose logs
+    $ # ...
+    $ docker-compose down
+
+
+Docker Swarm Mode
+-----------------
+
+OpenSlides may also be deployed in Swarm mode.  Distributing instances over
+multiple nodes may increase performance and offer failure resistance.
+
+An example configuration file, ``docker-stack.yml.m4``, is provided.  Unlike
+the Docker Compose setup, this configuration will most likely need to be
+customized, especially its placement constraints and database-related
+preferences.
+
+Before deploying an instance on Swarm, please see `Database Configuration`_ and
+`Backups`_, and review your ``docker-stack.yml``
+
+
+Database Configuration
+----------------------
+
+It is fairly easy to get an OpenSlides instance up an running; however, for
+production setups it is strongly advised to review the database configuration.
+
+By default, the primary database cluster will archive all WAL files in its
+volume.  Regularly pruning old data is left up to the host system, i.e., you.
+Alternatively, you may disable WAL archiving by setting
+``PGNODE_WAL_ARCHIVING=off`` in ``.env`` before starting the instance.
+
+The provided ``docker-stack.yml.m4`` file includes additional database
+services which can act as hot standby clusters with automatic failover
+functionality.  To take advantage of this setup, the database services need to
+be configured with proper placement constraints.  Before relying on this setup,
+please familiarize yourself with `repmgr <https://repmgr.org/>`_.
+
+
+Backups
+-------
+
+All important data is stored in the database.  Additionally, the project
+directory should be included in backups to ensure a smooth recovery.
+
+The primary database usually runs in the ``pgnode1`` service (but see `Database
+Configuration`_ above).
+.
+In some cases, it may be sufficient to generate SQL dumps with ``pg_dump``
+through ``docker exec`` to create backups.  However, for proper incremental
+backups, the host system can backup the cluster's data directory and WAL
+archives.
+
+The cluster's data directory is available as a volume on the host system.
+Additionally, the database archives its WAL files in the same volume by
+default.  This way, the host system can include the database volume in its
+regular filesystem-based backup routine and create efficient database backups
+suitable for point-in-time recovery.
+
+The `former management repository
+<https://github.com/OpenSlides/openslides-docker-compose/>`_ provides the
+script `openslides-pg-mgr.sh` which can enable Postgres' backup mode in all
+OpenSlides database containers.
+
+In Swarm mode, the primary database cluster may get placed on a number of
+nodes.  It is, therefore, crucial to restrict the placement of database
+services to nodes on which appropriate backups have been configured.
+
+
+Bugs, features and development
+================================
+
+Feel free to open issues here on GitHub! Please use the right templates for
+bugs and features, and use them correctly. Pull requests are also welcome; for
+a general overview of the development setup refer the `development instructions
+<https://github.com/OpenSlides/OpenSlides/blob/master/DEVELOPMENT.rst>`_.
