+Mopidy Pummeluff
+================
+
+Pummeluff is a `Mopidy <http://www.mopidy.com/>`_ extension which allows you to control Mopidy via RFID tags. It is as simple as that:
+
+- Register an action to an RFID tag
+- Touch that tag on the RFID reader and the action will be executed 
+
+Thus, the Mopidy Pummeluff extension adds the following features to Mopidy:
+
+- A radically simple web UI which can be used to manage the RFID tags
+- A daemon which continuously reads RFID tags in the background and executes the assigned actions
+
+There are several actions included, such as replacing the tracklist with a desired URI, setting the volume to a specific level or controlling the playback state.
+
+Hardware
+========
+
+Requirements
+------------
+
+To get the whole thing working, you need at least the following hardware:
+
+- A Raspberry Pi 3 Model B
+- An ``RC522`` RFID module (`RC522 on AliExpress <https://www.aliexpress.com/wholesale?SearchText=rc522>`_ for approx. *USD 1*)
+- RFID tags (``ISO 14443A`` & ``Mifare`` should work, `14443A tags on AliExpress <https://www.aliexpress.com/wholesale?SearchText=14443A+lot>`_ for approx. *0.4 USD* per tag)
+- Female dupont jumper wires (`female dupont jumper cables on AliExpress <https://www.aliexpress.com/wholesale?SearchText=dupont>`_ for approx. *1 USD*)
+
+Optionally you can also add two buttons to the RPi, which can be used for power & playback control:
+
+- Two momentary push buttons (`momentary push buttons on AliExpress <https://www.aliexpress.com/wholesale?SearchText=momentary+push+button>`_ for approx. *USD 1-2*) 
+
+Pummeluff also supports a status LED, which lights up when Pummeluff (i.e. Mopidy) is running. You can go with a separate LED, just make sure it can handle 3.3V or add a resistor. There are also push buttons with integrated LED's available, for example `these 5V momentary push buttons on AliExpress <https://www.aliexpress.com/item/16mm-Metal-brass-Push-Button-Switch-flat-round-illumination-ring-Latching-1NO-1NC-Car-press-button/32676526568.html>`_.
+
+.. note::
+
+    The project will probably run on other RPi models, but I've only tested it on the ``3B``. The RPi ``3B+`` should also work fine, as the GPIO pins are identical. I don't know about RPi ``1`` or ``2``, but you can give it a shot.
+
+Connecting the RC522 module
+---------------------------
+
+Please connect the ``RC522`` RFID module to the RPi as follows:
+
+- ``RC522 pin 1 [SDA ]`` ––– ``RPi pin 24 [SPI0 CE0 ]``
+- ``RC522 pin 2 [SCK ]`` ––– ``RPi pin 23 [SPI0 SCLK]``
+- ``RC522 pin 3 [MOSI]`` ––– ``RPi pin 19 [SPI0 MOSI]``
+- ``RC522 pin 4 [MISO]`` ––– ``RPi pin 21 [SPI0 MISO]``
+- ``RC522 pin 5 [IRQ ]`` ––– ``RPi pin 18 [ GPIO 24 ]``
+- ``RC522 pin 6 [GND ]`` ––– ``RPi pin 20 [   GND   ]``
+- ``RC522 pin 7 [RST ]`` ––– ``RPi pin 22 [ GPIO 25 ]``
+- ``RC522 pin 8 [3.3V]`` ––– ``RPi pin 17 [3.3V PWR ]``
+
+Please have a look at the `Raspberry Pi SPI pinout <https://pinout.xyz/pinout/spi>`_ if you want to have a graphical view of the RPi GPIO pins. 
+
+.. note::
+    
+    This connections are only valid for the RPi model ``3B`` and ``3B+``. If you want to use another RPI model, make sure you're using the correct pins.
+
+Connecting the buttons (optional)
+---------------------------------
+
+You can connect two buttons to the RPi:
+
+- ``RPi pin 5`` - Power button: Shutdown the Raspberry Pi into halt state & wake it up again from halt state
+- ``RPi pin 29`` - Playback button: Pause and resume the playback
+- ``RPi pin 31`` - Stop button: Stops the playback
+- ``RPi pin 33`` - Previous button: Changes to the previous track in the playlist
+- ``RPi pin 35`` - Next button: Changes to the next track in the playlist
+
+The buttons must shortcut their corresponding pins against ``GND`` (e.g. pin ``6``) when pressed. This means you want to connect one pin of the button (i.e. ``C``) to RPI's ``GND``, and the other one (i.e. ``NO``) to RPi's pin ``5``, ``29``, ``31``, ``33`` or ``35``.
+
+Connecting the status LED (optional)
+------------------------------------
+
+If you want to have a status LED which is turned on when the RPi is running, you can connect an LED to a ``GND`` pin (e.g. pin ``6``) & to pin ``8``.
+
+Installation
+============
+
+Prepare Raspberry Pi
+--------------------
+
+Before you can install and use Mopidy Pummeluff, you need to configure your Raspberry Pi properly.
+
+We want to enable the ``SPI`` interface and give the ``mopidy`` user access to it. This is required for the communication to the RFID module. Enter this command:
+
+.. code-block:: bash
+
+    sudo raspi-config
+
+In the configuraton utility, **Enable the SPI** under ``5 Interfacing Options – P4 SPI``. 
+
+After that, add your ``mopidy`` user to the ``spi`` and ``gpio`` group:
+
+.. code-block:: bash
+
+    sudo usermod -a -G spi,gpio mopidy
+
+If you're planning to use a button or RFID tag to shutdown the system, you also need to create a sudo rule, so that the ``mopidy`` user can shutdown the system without a password prompt:
+
+.. code-block:: bash
+
+    echo "mopidy ALL = NOPASSWD: /sbin/shutdown" > /etc/sudoers.d/mopidy
+
+Install via pip
+---------------
+
+The recommended way to install Mopidy Pummeluff by using ``pip`` and thus by executing the following command:
+
+.. code-block:: bash
+
+    sudo pip install mopidy-pummeluff
+
+.. hint::
+
+    If you get an error that ``spidev`` could not be found, run ``pip install spidev`` first. This is an issue related to the ``pi-rc522`` Pypi package.
+
+Install from source
+-------------------
+
+Alternatively, you can also install Mopidy Pummeluff from source, by running this command:
+
+.. code-block:: bash
+
+    sudo su -
+    cd /usr/src
+    git clone https://github.com/confirm/mopidy-pummeluff.git
+    cd mopidy-pummeluff
+    python setup.py install
+
+.. hint::
+
+    If you get an error that ``spidev`` could not be found, run ``pip install spidev`` first. This is an issue related to the ``pi-rc522`` Pypi package.
+
+Configuration
+=============
+
+Activate and configure the `Mopidy HTTP <https://docs.mopidy.com/en/latest/ext/http/>`_ extension and make sure you can connect to the Web UI. The minimal config looks like this:
+
+.. code-block::
+
+    [http]
+    enabled = true
+    hostname = 0.0.0.0
+
+Usage
+=====
+
+Open the Mopidy Web UI (i.e. ``http://{MOPIDY_IP}:6680/``).
+You should see a ``pummeluff`` web client which can be used to regsiter new RFID tags.
+
+Contribution
+============
+
+Please follow `these development guidelines <https://development-guidelines.confirm.ch/>`_ when contributing to this project.
