 Installation
 ------------
 
-For Debian testing or unstable there is an official public repository
-provided by AG Projects. Install the AG Projects debian software signing
-key:
+For Debian packages go to:
 
-wget http://download.ag-projects.com/agp-debian-gpg.key
-apt-key add agp-debian-gpg.key
+https://docs-new.sipthor.net/w/debian_package_repositories/
 
-Add these lines in etc/apt/sources.list
+sduo apt-get update
+sudo apt-get install msrprelay
 
-# AG Projects software
-deb http://ag-projects.com/debian unstable main
-deb-src http://ag-projects.com/debian unstable main
-
-After that, run:
-
-apt-get update
-apt-get install msrprelay
 
 If you have installed the debian package you can skip forward to the
 'Configure the server' section.
 
 For non Debian installations you must perform the following steps:
 
  * Download and install dependencies
  * Download and install MSRPRelay
 
 
 Download and install dependencies
 ---------------------------------
 
 The software has been developed and tested on Linux Debian unstable
 distribution.
 
 The software has the following dependencies:
 
- * Python >=2.5 http://python.org
- * Twisted >=2.5.0 http://twistedmatrix.com
- * GnuTLS >=2.4.1 http://www.gnu.org/software/gnutls/
- * python-gnutls >=1.1.8 http://pypi.python.org/pypi/python-gnutls/
- * python-application >=1.2.8 http://pypi.python.org/pypi/python-application
- * SQLObject >= 0.10.2 http://sqlobject.org
+ * Python 3
+ * Twisted
+ * SQLObject
+ * python3-application http://download.ag-projects.com/SipSimpleSDK/Python3/
+ * python-gnutls http://download.ag-projects.com/SipSimpleSDK/Python3/
 
 
 Download and install MSRPRelay
 ------------------------------
 
 The software can be downloaded as a tar archive from:
 
 http://download.ag-projects.com/MSRPRelay/
 
 Extract it using tar xzvf msrprelay-version.tar.gz and change directory to
 the newly created msrprelay directory.
 
 The source code is managed using darcs version control tool. The darcs
 repository can be fetched with:
 
-darcs get http://devel.ag-projects.com/repositories/msrprelay
+darcs clone http://devel.ag-projects.com/repositories/msrprelay
+
 
 To obtain the incremental changes after the initial get, go to the msrprelay
 directory and run:
 
 cd msrprelay
 darcs pull -a
 
 Install the software:
 
 cd msrprelay
-python setup.py install
+python3 setup.py install
 
 
 Configure the server
 --------------------
 
 A sample configuration file is provided as config.ini.sample. All configuration
 options are documented in this file.
 
 Configure MSRPRelay by copying config.ini.sample to config.ini and editing
 it.  At the very least the certificates need to be provided and the
 authentication backend needs to be configured.
 
 Generate a TLS certificate/key pair. For documentation on how to do this,
 see the "tls" directory.
 
 Typically, both TLS certificate/key pair and configuration file would be
 installed in /etc/msrprelay. This is not needed however, as MSRPRelay looks
 for the configuration file in its local directory. Alternatively, the
 configuration filename and location may be specified on the command line
 using the --config-file option.
 
 If you don't have a running user database to connect to you can test using
 the in-memory backend as described.
 
 The software will reload its configuration file when it receives the HUP
 signal. All of the already established sessions will continue to operate using
 the old settings until a disconnection occurs within this session. This allows
 for changes in the configuration without disruption of service.
 
 Note: at this moment the backend configurations are not re-read.
 
 
 Configure the DNS
 -----------------
 
 For each domain served by the relay the following DNS record must be added to
 the name servers authoritative for the domain:
 
 _msrps._tcp.example.com. IN SRV	0 0 2855 msrprelay.example.com.
 msrprelay.example.com. IN A 10.0.0.1
 
 Replace the domain name, hostname and IP address with the real ones.
 
 
 Running the server
 ------------------
 
 Start the MSRPRelay, either by executing:
 
-./msrprelay --no-fork
+sudo ./msrprelay --no-fork
 
 or as a daemon, which is the default behaviour.
 
-This can also be done using the init.d script:
+This can also be done using the systemd script:
 
-/etc/init.d/msrprelay start
+sudo systemctl start msrprelay
 
 When started as a deamon MSRPRelay will log its messages to syslog.
 
 
 Testing the server
 ------------------
 
 The "test/" directory contains a number of test scripts and a simple file
 transfer sender and receiver. See the README in the "test/" directory for
 documentation on the latter.
 
 You can use Blink client for IM and file Transfer from http://icanblink.com
 or comand line tools from SIP Simple Client SDK http://sipsimpleclient.com.
