 This emulation platform was created to support network  service developers to locally prototype and test complete network service chains in realistic end-to-end multi-PoP scenarios. It allows the direct execution of real network functions, packaged as Docker containers, in emulated network topologies running locally on the network service developer's machine.

 ### Contributing

-(if applicable) Description (encouraging) how to contribute to this project/repository.
+Contributing to the Gatekeeper is really easy. You must:
+
+1. Clone [this repository](http://github.com/sonata-nfv/son-emu);
+2. Work on your proposed changes, preferably through submiting [issues](https://github.com/sonata-nfv/son-emu/issues);
+3. Submit a Pull Request;
+4. Follow/answer related [issues](https://github.com/sonata-nfv/son-emu/issues) (see Feedback-Chanel, below).

 
 ## Installation
 
 ## Installation

-(if applicable) Describe briefly how to install the software. You may want to put a link to son-install instead:
+There are two ways to install and use son-emu. The simple one is to use Vagrant to create a VirtualBox-based VM on you machine that contains the pre-installed and configured emulator. The more complicated installation requires a freshly installed Ubuntu 14.04 LTS or 16.04 LTS and is done by a ansible playbook.
+
+### Vagrant Installation
+
+* Request VirtualBox and Vagrant to be installed on the system.
+* `git clone https://github.com/sonata-nfv/son-emu.git`
+* `cd ~/son-emu`
+* `vagrant up`
+* `vagrant ssh` to enter the new VM in which the emulator is installed.
+
+Follow the MOTD in the VM to run the example topology and the dummy-gatekeeper. The dummy-gatekeeper's default port 5000 is forwarded to the host machine and can be accessed from it by using, e.g., curl http://127.0.0.1:5000/packages.

 
 

-The installation of this component can be done using the [son-install](https://github.com/sonata-nfv/son-install) script.
+### Ansible Installation
+
+* Requires: Ubuntu 14.04 LTS or 16.04 LTS
+* `sudo apt-get install ansible git`
+* `sudo vim /etc/ansible/hosts`
+* Add: `localhost ansible_connection=local`
+
+#### 1. Containernet
+* `cd`
+* `git clone https://github.com/mpeuster/containernet.git`
+* `cd ~/containernet/ansible`
+* `sudo ansible-playbook install.yml`
+* Wait (and have a coffee) ...
+
+#### 2. Emulator
+* `cd`
+* `git clone https://github.com/sonata-nfv/son-emu.git`
+* `cd ~/son-emu/ansible`
+* `sudo ansible-playbook install.yml`
