+# mDNS / DNS-SD library
+
+The four files in this directory implement mDNS / DNS-SD lookup and are
+vendored from third-party sources:
+
+## mdns.h, mdns.c
+
+mDNS / DNS-SD lookup library by Mattias Jansson. Originally released to
+the public domain at https://github.com/mjansson/mdns.
+
+The exact files here were taken from CrealityOfficial/CrealityPrint
+v7.1.1, which split the upstream header-only library into separate
+declaration (mdns.h) and implementation (mdns.c) files.
+
+- Source: https://github.com/mjansson/mdns
+- License: Public domain (no restrictions on use)
+
+## cxmdns.h, cxmdns.cpp
+
+Thin C++ wrapper over mdns.{h,c} that exposes a single function:
+
+  std::vector<machine_info> syncDiscoveryService(
+      const std::vector<std::string>& prefix);
+
+It sends a DNS-SD meta-discovery query (`_services._dns-sd._udp.local.`),
+listens for ~5 seconds, and returns `{ip, service_name}` for every
+service announcement whose name contains any of the given prefixes.
+
+OrcaSlicer uses this to find Creality K-series printers on the LAN
+(service-name prefix "Creality"), since K-series firmware announces
+each printer under a per-device-unique service type
+`_Creality-<MAC-derived-hex>._udp.local.` that no fixed-name query can
+target.
