+#PC/SC Relay
+
+Welcome to PC/SC Relay. The purpose of PC/SC Relay is to relay a smart
+card using an contact-less interface. Currently the following contact-less
+emulators are supported:
+
+- Hardware supported by [libnfc](http://www.libnfc.org/)
+- OpenPICC
+- [Android Smart Card
+  Emulator](http://frankmorgner.github.io/vsmartcard/ACardEmulator/README.html)
+
+Command APDUs are received with the contact-less interface and relayed. The
+Response APDUs are then sent back via RFID. The contact-less data will be
+relayed to one of the following:
+
+- to a *real* smart card inserted into one of the systems' smart card readers.
+  The smart card reader must be accessible with PC/SC. The smart card may be
+  contact-based *or* contact-less.
+- to a [virtual smart
+  card](http://frankmorgner.github.io/vsmartcard/ccid/README.html) that
+  directly connects to `pcsc-relay`. The virtual smart card's native interface
+  is used and (despite its name) PC/SC Relay does not need to access PC/SC in
+  this case.
