 # Overview
 The repository includes everything needed to build an LED strip music visualizer (excluding hardware):
 
-- Python Real-time visualization, which includes code for:
+- Python real-time visualization code, which includes code for:
   - Recording audio with a microphone ([microphone.py](python/microphone.py))
   - Digital signal processing ([dsp.py](python/dsp.py))
   - Constructing 1D visualizations ([visualization.py](python/visualization.py))
   - Sending pixel information to the ESP8266 over WiFi ([led.py](python/led.py))
 - Arduino firmware for the ESP8266 ([ws2812_controller.ino](arduino/ws2812_controller/ws2812_controller.ino))
 
+# What do I need to make one?
+The following hardware is needed to build an LED strip music visualizer:
+- Computer with Python 2.7 or 3.5 ([Anaconda](https://www.continuum.io/downloads) is recommended on Windows)
+- Any ESP8266 module with RX1 pin exposed. These modules are known to be compatible (but many others work too):
+  - NodeMCU v3
+  - Adafruit HUZZAH
+  - Adafruit Feather HUZZAH
+ - Any ws2812b LED strip (such as Adafruit Neopixels)
 
+# Dependencies
+## Python
+There are only a handful of Python dependencies:
+- Numpy
+- Scipy (for digital signal processing)
+- PyQtGraph (for GUI visualization)
+- PyAudio (for recording audio with microphone)
 
+On Windows machines, the use of [Anaconda](https://www.continuum.io/downloads) is **highly recommended**. Anaconda simplifies the installation of Python dependencies, which is sometimes difficult on Windows.
 
+# Arduino dependencies
+The [ws2812b i2s library](https://github.com/JoDaNl/esp8266_ws2812_i2s) must be downloaded and installed in the Arduino libraries folder.
