+Hardware program of the game Taiko Sanro.
+
+## What is This Program
+
+Music game fans from East Asia countries are most probable to know a famous game called Taiko No Tatsujin (太鼓の達人), developed by Bandai Namco Games of Japan. This program aims to help you develop your own **hardware taiko** at home, just like how you play Taiko in arcade halls.
+
+## Features
+
+* **Full support for the PC game Taiko-san Jiro (太鼓さん次郎).** Actually, any app using keyboards as input is supported.
+* **Force-sensitive.** I am also developing a new open-source game called Taiko Sanro that can support this feature.
+* **Supports dense inputs such as rolling.**
+
+*In all, if you configure the program well enough, your taiko will perform exactly the same as the arcade version! :D*
+
+## Prerequisites
+
+Because this is a DIY project, you should have some basic  electronic engineering knowledge about connecting microprocessors with jumper wires on a breadboard. **Soldering techniques are NOT required.**
+
+## Getting Started
+
+It might take you a few days to assembly and configure your own taiko device. The chips are cheap, though, you can buy them from wherever you want.
+
+### Preparation
+
+* Arduino Micro board x 1
+* Keyes K-036 microphone module x 4
+* Breadboard x 1
+* A few jumper wires
+* Micro-USB to USB cable x 1
+* [Arduino IDE](https://www.arduino.cc/en/Main/Software)
+* Wood planks x 4, shaped like [this]()
+
+A few things to note:
+
+1. Any Arduino modules with ATmega32u4 chips or Due and Zero boards are supported. Arduino Micro is the cheapest one, though.
+2. Using a breadboard is a low-cost option, but it is not the best/stablest choice. I made a PCB blueprint that allows you to print the integrated board and solder up.
+3. You can also design build your own microphones modules, just make sure you know how to connect them to your Arduino module.
+4. About the wood planks: solid, dense and heavy wood is the best choice, while plywoods, particleboard and medium-density fiberboard (MDF) is fragile at edges and can be easily damaged.
+
+### Connecting the Parts
+
+The schema is quite simple. Each microphone module has 4 pins, and we only need 3 of them (`A0`, `+`, and `G`). Simply connect their `A0` outputs to Arduino Micro's `A0`~`A3` inputs, then connect their `+` pins together with module's `5V` pin, then the `G` pins together to the ground. Use the following picture if you have any problems.
+
+### Uploading the Program
+
+1. Create a folder and put the source files (`sanro.ino` and `cache.h`) into it.
+2. Download and install [Arduino IDE](https://www.arduino.cc/en/Main/Software).
+3. Connect your Arduino Micro to your computer with a USB cable. The driver installation should be automatic, but if you have any questions about it, [check this official guide](https://www.arduino.cc/en/Guide/ArduinoLeonardoMicro#toc8).
+4. Open the `sanro` project in Arduino IDE.
+5. Select "Board" - "Arduino/Genuino Micro" from the menu.
+6. Compile and upload the program.
