-## Development
-(if applicable)
+A short demo that showcases son-emu together with its dummy gatekeeper is available [here](https://youtu.be/BgWDp5CM0io).
+
+### Development
+
+To install the emulator package in development mode, do:
+
+* `python setup.py develop`

+* `ansible`
+* `misc`
+* `src` 
+ * `emuvim`
+  * `api`
+   * `rest` REST API for son-emu-cli
+   * `sonata` Dummy gatekeeper API
+  * `cli` Command line client to control the emulator
+  * `dcemulator` Emulator core
+   * `resourcemodel` Resource limitation models
+  * `examples` Example topology scripts
+  * `test` Test scripts
+* `utils` Helper scripts for SONATA's CI/CD setup
+
+
+#### Run Unit Tests
+* `cd ~/son-emu`
+* `sudo py.test -v src/emuvim/test/unittests`
+
 
 ### Building
-Describe briefly how to build the software.
+
+Son-emu is entirely written in Python and does not require a special build process. Please check the [Installation](https://github.com/sonata-nfv/son-emu#installation) section for more details about the installation of son-emu.
 
 ### Dependencies
 
+Son-emu requires the latest version of [Containernet](https://github.com/mpeuster/containernet) to be installed on the system.
+
+Despite of this son-emu has the following dependencies:

 * [argparse](https://pypi.python.org/pypi/argparse) >= 1.4.0 (Python software foundation License)
 * [docker-py](https://pypi.python.org/pypi/docker-py) == 1.7.1(Apache 2.0)

 ## Usage
-(if applicable) Describe briefly how to use the software.
 
-### CLI
+### Examples
+#### Manual Usage Example:
+
+This simple example shows how to start the emulator with a simple topology (terminal 1) and how to start (terminal 2) some empty VNF containers in the emulated datacenters (PoPs) by using the son-emu-cli.
+
+* First terminal (start the emulation platform):
+ * `sudo python src/emuvim/examples/simple_topology.py`
+* Second terminal:
+ * `son-emu-cli compute start -d datacenter1 -n vnf1`
+ * `son-emu-cli compute start -d datacenter1 -n vnf2`
+ * `son-emu-cli compute list`
+* First terminal:
+ * `containernet> vnf1 ifconfig`
+ * `containernet> vnf1 ping -c 2 vnf2`
+
+#### Dummy Gatekeeper Example:
+
+This example shows how to deploy a SONATA example package in the emulator using the dummy gatekeeper.
+
+* First terminal (start the emulation platform):
+ * `sudo python src/emuvim/examples/sonata_y1_demo_topology_1.py`
+* Second terminal (deploy the example package):
+ * Upload: `curl -i -X POST -F package=@sonata-demo-docker.son http://127.0.0.1:5000/packages`
+ * Instantiate: `curl -X POST http://127.0.0.1:5000/instantiations -d "{}"`
+ * Verify that service runs: `son-emu-cli compute list`
+
+
