-  <pre><strong>icmplib 2.0 is here! 🎉</strong>
-
-To celebrate its first year and its integration into popular projects,
-icmplib has been completely revised! Thanks to its advanced features,
-including the ability to use the library without root privileges, QoS and
-increased compatibility with all modern operating systems, it becomes the
-most advanced library in its category. Many things are yet to come!

   <pre>icmplib is a brand new and modern implementation of the ICMP protocol in Python.

 - Raises a `NameLookupError` exception if the requested name does not exist or cannot be resolved.
 
+### How to use the library without root privileges?
+Since its version 2.0, icmplib can be used without root privileges.
+
+For this, you can set the `privileged` parameter to `False` on the `ping` and `multiping` functions, as well as the low level classes. By disabling this parameter, the kernel handles some parts of the ICMP headers.
+
+On some Linux systems, you must allow this feature:
+
+```shell
+$ sudo sysctl -w net.ipv4.ping_group_range='0 2147483647'
+net.ipv4.ping_group_range = 0 2147483647
+```
+
+*Since Ubuntu 20.04 LTS, this manipulation is no longer necessary.*

 ### Why I have no response from a remote host?
 In the event of no response from a remote host, several causes are possible:
 - Your computer's firewall may not be properly configured. This impacts in particular the `traceroute` function which can no longer receive ICMP Time Exceeded messages.

 - The remote host or an upstream gateway drops ICMP messages for security reasons.
 - In the case of the `traceroute` function, if the last host in the list is not the one expected, more than 30 hops (default) may be needed to reach it. You can try increasing the value of the `max_hops` parameter.
