+# Coffee Reading
+
+A command-line parser for Wii U OTP/SEEPROMs. 
+
+Coffee Reading is a tool that can be run through Command Prompt or Terminal to parse Wii U [OTP (one-time programmable)](https://wiiubrew.org/wiki/Hardware/OTP) or [SEEPROM (serial electrically erasable programmable read only memory)](https://wiiubrew.org/wiki/Hardware/SEEPROM) files and present them in an easily-readable format. Please do not share any values obtained from this program! Many are illegal to share due to copyright law and/or unique to your own console!
+
+## Installation
+A Windows executable will be bundled with each release. Linux users will need to use the Python script in the source code in order to run the program.
+
+## Usage
+A Wii U OTP or SEEPROM file is most commonly obtained when following our [hacking guide](https://wiiu.hacks.guide/), with the help of [wiiu-nanddumper](https://github.com/wiiu-env/wiiu-nanddumper-payload/).
+* Call the executable file and provide the path to your dumped one-time programmable. By default, only unique values are shown in the program. In order to read the entire file, pass `--unknown` (or `-u`) as an argument.
+* The ability to save a report of obtained values is also available. Provide `--save` (or `-s`) as an argument to the program to do so. A text file named with a timestamp will be generated in the same directory as the tool. This can be used to refer to certain values without having to run the program again in the future.
+
+Example inputs may include:
+* `Klefki.exe -s -u otp.bin`
+* `./Klefki -s -u otp.bin`
