Introduction
------------

LibreNMS is an auto-discovering PHP/MySQL/SNMP based network monitoring
which includes support for a wide range of network hardware and operating
systems including Cisco, Linux, FreeBSD, Juniper, Brocade, Foundry, HP and
many more.

We intend LibreNMS to be a viable project and community that:
- encourages contribution,
- focuses on the needs of its users, and
- offers a welcoming, friendly environment for everyone.

The [Debian Social Contract][10] will be the basis of our priority system,
and mutual respect is the basis of our behavior towards others.
