# KDE DNS-SD
Network service discovery using Zeroconf
## Introduction
KDNSSD is a library for handling the DNS-based Service Discovery Protocol
(DNS-SD), the layer of [Zeroconf](http://www.zeroconf.org) that allows network
services, such as printers, to be discovered without any user intervention or
centralized infrastructure.
## Usage
If you are using CMake, you need to have
find_package(KF5DNSSD NO_MODULE)
(or similar) in your CMakeLists.txt file, and you need to link to KF5::DNSSD.
If you are writing an application that wants to discover services on the
network, use DNSSD::ServiceBrowser. You can also find available service types
using ServiceTypeBrowser.
If you want to announce the availability of a service provided by your
application, use DNSSD::PublicService.
DNSSD::DomainBrowser allows you to find domains (other than the local one)
recommended for browsing or publishing to.
Note that DNSSD::ServiceBrowser::isAvailable() provides information about the
availability of the services provided by this library generally, not just for
browsing services.
## More information
More information about DNS-SD can be found in the [online
documentation][appledocs] for Apple's implementation of Zeroconf,
