-Scapy is a powerful Python-based interactive packet manipulation
-program and library.
 
-It is able to forge or decode packets of a wide number of protocols,
-send them on the wire, capture them, match requests and replies, and
-much more.
+Scapy is a powerful Python-based interactive packet manipulation program and
+library.
 
-It can easily handle most classical tasks like scanning, tracerouting,
-probing, unit tests, attacks or network discovery (it can replace
-hping, 85% of nmap, arpspoof, arp-sk, arping, tcpdump, tethereal, p0f,
-etc.). It also performs very well at a lot of other specific tasks
-that most other tools can't handle, like sending invalid frames,
-injecting your own 802.11 frames, combining technics (VLAN hopping+ARP
-cache poisoning, VOIP decoding on WEP encrypted channel, ...),
-etc.

+designed to allow fast packet prototyping by using default values that work.
 
-# Installation #
+It can easily handle most classical tasks like scanning, tracerouting, probing,
+unit tests, attacks or network discovery (it can replace `hping`, 85% of `nmap̀`,
+`arpspoof`, `arp-sk`, `arping`, `tcpdump`, `wireshark`, `p0f`, etc.). It also
+performs very well at a lot of other specific tasks that most other tools can't
+handle, like sending invalid frames, injecting your own 802.11 frames, combining
+techniques (VLAN hopping+ARP cache poisoning, VoIP decoding on WEP protected
+channel, ...), etc.
 
-Scapy works without any external Python modules on Linux and BSD like operating systems. On Windows, you need to install some mandatory dependencies as described in the documentation.
 
-To benefit from all Scapy features, you might want to install Python modules, such as matplotlib or cryptography.
+## Hands-on ##
 
-See the [tutorial](http://scapy.readthedocs.io/en/latest/installation.html) and follow the instructions to install scapy.
+### Interactive shell ###
 
-## Tutorial ##
+Scapy can easily be used as an interactive shell to interact with the network.
+The following example shows how to send an ICMP Echo Request message to
+`github.com`, then display the reply source IP address:
 
-To begin with scapy, see the
-[interactive tutorial](http://scapy.readthedocs.io/en/latest/usage.html#interactive-tutorial)
-and
-[the quick demo: an interactive session](http://scapy.readthedocs.io/en/latest/introduction.html#quick-demo)
-(some examples may be outdated).
+```python
+sudo ./run_scapy 
+Welcome to Scapy
+>>> p = IP(dst="github.com")/ICMP()
+>>> r = sr1(p)
+Begin emission:
+.Finished to send 1 packets.
+*
+Received 2 packets, got 1 answers, remaining 0 packets
+>>> r[IP].src
+'192.30.253.113'
+```

+It is straightforward to use Scapy as a regular Python module, for example to
+check if a TCP port is opened. First, save the following code in a file names
+`send_tcp_syn.py`
+
+```python
+from scapy.all import *
+conf.verb = 0
+
+p = IP(dst="github.com")/TCP()
+r = sr1(p)
+print r.summary()
+```
+
+Then, launch the script with:
+```python
+sudo python send_tcp_syn.py
+IP / TCP 192.30.253.113:http > 192.168.46.10:ftp_data SA / Padding
+```
