-# PAT80 Emulator
+# Pat80 emulator
-This folder contains a submodule (you should fetch it if you need to run the os in an emulator).
 
-Uses cburbridge's Z80 emulator written in python. It opens some windows showing the emulated computer's memory map, the cpu registers state and parallel terminal to interact with the os.
+## Setup
+
+Install the required Z80 emulator by redcode following the instructions for your Linux distribution at https://github.com/redcode/Z80
+Make sure to install not only the `libz80` package, but also `libz80-dev`.
+
+Create the build directory: `mkdir build`
+Create the makefile with cmake: `cd build && cmake ..`
+
+## Build
+
+Enter the `build` directory and run `make`
 
 ## Usage
-To run the os in the emulator, head to `pat80-computer/software/z80-assembly/os/Makefile` and run `make run` to build the rom from assembly and start the emulator.
