-ejabberd is a distributed, fault-tolerant technology that allows the creation
-of large-scale instant messaging applications. The server can reliably support
-thousands of simultaneous users on a single node and has been designed to
-provide exceptional standards of fault tolerance. As an open source
-technology, based on industry-standards, ejabberd can be used to build bespoke
-solutions very cost effectively.
 
+[ejabberd][im] is an open-source,
+robust, scalable and extensible realtime platform built using [Erlang/OTP][erlang],
+that includes [XMPP][xmpp] Server, [MQTT][mqtt] Broker and [SIP][sip] Service.
 
-Key Features
-------------
-
-- **Cross-platform**  
-  ejabberd runs under Microsoft Windows and Unix-derived systems such as
-  Linux, FreeBSD and NetBSD.
-
-- **Distributed**  
-  You can run ejabberd on a cluster of machines and all of them will serve the
-  same XMPP domain(s). When you need more capacity you can simply add a new
-  cheap node to your cluster. Accordingly, you do not need to buy an expensive
-  high-end machine to support tens of thousands concurrent users.
-
-- **Fault-tolerant**  
-  You can deploy an ejabberd cluster so that all the information required for
-  a properly working service will be replicated permanently on all nodes. This
-  means that if one of the nodes crashes, the others will continue working
-  without disruption. In addition, nodes also can be added or replaced ‘on
-  the fly’.
-
-- **Administrator-friendly**  
-  ejabberd is built on top of the Open Source Erlang. As a result you do not
-  need to install an external database, an external web server, amongst others
-  because everything is already included, and ready to run out of the box.
-  Other administrator benefits include:
-  - Comprehensive documentation.
-  - Straightforward installers for Linux.
-  - Docker packaging to help with deploy / development on Linux, Windows or MacOS.
-  - Deb and RPM packaging to support most Linux distributions.
-  - Web administration.
-  - Shared roster groups.
-  - Command line administration tool.
-  - Can integrate with existing authentication mechanisms.
-  - Capability to send announce messages.
-
-- **Internationalized**  
-  ejabberd leads in internationalization. Hence it is very well suited in a
-  globalized world. Related features are:
-  - Translated to 25 languages.
-  - Support for IDNA.
-
-- **Open Standards**  
-  ejabberd is the first Open Source XMPP server claiming to fully comply to
-  the XMPP standard.
-  - Fully XMPP-compliant.
-  - XML-based protocol.
-  - Many protocols supported.
-
-
-Additional Features
--------------------
-
-Moreover, ejabberd comes with a wide range of other state-of-the-art features:
-
-- **Modularity**
-  - Load only the modules you want.
-  - Extend ejabberd with your own custom modules.
-
-- **Security**
-  - SASL and STARTTLS for c2s and s2s connections.
-  - STARTTLS and Dialback s2s connections.
-  - Web Admin accessible via HTTPS secure access.
-
-- **Databases**
-  - Internal database for fast deployment (Mnesia).
-  - Native MySQL support.
-  - Native PostgreSQL support.
-  - ODBC data storage support.
-  - Microsoft SQL Server support.
-
-- **Authentication**
-  - Internal authentication.
-  - PAM, LDAP and ODBC.
-  - External authentication script.
-
-- **Others**
-  - Support for virtual hosting.
-  - Compressing XML streams with Stream Compression (XEP-0138).
-  - Statistics via Statistics Gathering (XEP-0039).
-  - IPv6 support both for c2s and s2s connections.
-  - Multi-User Chat module with support for clustering and HTML logging.
-  - Users Directory based on users vCards.
-  - Publish-Subscribe component with support for Personal Eventing.
-  - Support for web clients: HTTP Polling and HTTP Binding (BOSH).
-  - Component support: interface with networks such as AIM, ICQ and MSN.

-Quickstart guide
-----------------
-
-### 0. Requirements
-
-To compile ejabberd you need:
-
- - GNU Make.
- - GCC.
- - Libexpat ≥ 1.95.
- - Libyaml ≥ 0.1.4.
- - Erlang/OTP ≥ 19.3.
- - OpenSSL ≥ 1.0.0.
- - Zlib ≥ 1.2.3, for Stream Compression support (XEP-0138). Optional.
- - PAM library. Optional. For Pluggable Authentication Modules (PAM).
- - ImageMagick's Convert program and Ghostscript fonts. Optional. For CAPTCHA
-   challenges.
- - Elixir ≥ 1.10.3. Optional. Alternative to build ejabberd
-
-If your system splits packages in libraries and development headers, you must
-install the development packages also.
-
-### 1. Compile and install on *nix systems
+Check the features in [ejabberd.im][im], [ejabberd Docs][features],
+[ejabberd at ProcessOne][p1home], and a list of [supported protocols and XEPs][xeps].
 
-To compile ejabberd, execute the following commands.  The first one is only
-necessary if your source tree didn't come with a `configure` script (In this
-case you need autoconf installed).
-
-    ./autogen.sh
-    ./configure
-    make
-
-To install ejabberd, run this command with system administrator rights (root
-user):
-
-    sudo make install
-
-These commands will:
-
-- Install the configuration files in `/etc/ejabberd/`
-- Install ejabberd binary, header and runtime files in `/lib/ejabberd/`
-- Install the administration script: `/sbin/ejabberdctl`
-- Install ejabberd documentation in `/share/doc/ejabberd/`
-- Create a spool directory: `/var/lib/ejabberd/`
-- Create a directory for log files: `/var/log/ejabberd/`
-
-
-### 2. Start ejabberd
-
-You can use the `ejabberdctl` command line administration script to
-start and stop ejabberd. For example:
-
-    ejabberdctl start
-
-
-For detailed information please refer to the
-[ejabberd Documentation](https://docs.ejabberd.im)
 
+Installation
+------------
 
-### 3. Use ejabberd locally
+There are several ways to install ejabberd:
 
-Alternatively, you can setup ejabberd without installing in your system:
+- Source code: compile yourself, see [COMPILE](COMPILE.md)
+- Installers from [ProcessOne Downloads][p1dl] (run/deb/rpm for x64)
+- Installers from [ejabberd GitHub Releases][releases] (run/deb/rpm for x64 and arm64)
+- Container image from [ejabberd Docker Hub][hubecs], see [ecs README][docker-ecs-readme] (for x64)
+- Container image from [ejabberd Github Packages][packages], see [CONTAINER](CONTAINER.md) (for x64 and arm64)
+- Using your [Operating System package][osp]
+- Using the [Homebrew][homebrew] package manager
 
-    ./configure --with-rebar=rebar3
-    make dev
 
-Or, if you have Elixir available and plan to develop Elixir code:
+Documentation
+-------------
 
-    ./configure --with-rebar=mix
-    make dev
+Please check the [ejabberd Docs][docs] website.
 
-Check the full list of targets:
+When compiling from source code, you can get some help with:
 
+    ./configure --help
     make help
 
+Once ejabberd is installed, try:
 
-Translation
------------
-
-Using any gettext editor, you can improve the translation files found in
-`priv/msgs/*.po`, and then submit your changes.
+    ejabberdctl help
+    man ejabberd.yml
 
-Alternatively, a simple way to improve translations is using our Weblate project:
