+# Rasperry Pi RFID Jukebox
+
+Disclaimer: this is a perpetual work in progress!
+
+This is a personal project of [Annika Backstrom][1] for using a Raspberry Pi as
+an RFID-controlled "jukebox". Given an RPi with attached MFRC522, UIDs from 1K
+MIFARE tags can be associated with media (MP3 files) and actions (currently,
+STOP and PAUSE).
+
+## Components
+
+* Jukebox app with web frontend (node.js)
+* RFID tag reader (Python)
+* MP3 player (mpg321, not included)
+
+## Setup
+
+This section is incomplete (of course) and parts are tuned to my setup and
+for my own convenience:
+
+1. Clone project
+2. Copy config.json.sample to config.json
+3. Edit config.json for your setup
+4. `npm install` (node.js dependencies)
+5. `make all` (Python dependencies, mpg321 dependency)
+
+TODO: Can this be streamlined? Maybe move Makefile commands into `npm` commands.
+
+## config.json
+
+The following keys are available:
+
+* `port` -- web server port
+* `tag_reader` -- path to tag reader script. jukebox expects the tag reader to
+  spit out a unique string for each tag (e.g. 10 character hex UID)
+* `mpg321` -- path to mpg321 executable. should be run in "remote control" mode
+  (`-R`), reading commands from stdin.
+* `stop_id` -- id of the card that stops playback
+* `pause_id` -- id of card that pauses playback
