 # yacemu (Yet Another Chip Eight Emulator)
-A Chip-8 emulator written in C. Depends on SDL2.
+A Chip-8 emulator (interpereter) written in C. Depends on SDL2.
+
+### Building & Testing 
+
+In order to run yacemu, you must have sdl2 and make installed.
+
+Once you have the dependencies installed, you can build the emulator with:
+```shell
+make build
+```
+
+You can build start the emulator with:
+```shell
+make run ROM_FILE=[PATH_TO_YOUR_ROM]
+```
+
+If you would like to run it in turbo mode (faster emulation, useful for testing) then run:
+```shell
+make run-turbo ROM_FILE=[PATH_TO_YOUR_ROM]
+```
+
+If you would like to debug with gdb then run:
+```shell
+make debug ROM_FILE=[PATH_TO_YOUR_ROM]
+```
+
+If you would like to debug with gdb in turbo mode then run:
+```shell
+make debug-turbo ROM_FILE=[PATH_TO_YOUR_ROM]
+```
+
+### Running
+
+If you have a binary, you can run it with the following:
+
+```shell
+yacemu [PATH_TO_YOUR_ROM]
+```
+
+If you would like to run it in turbo mode (faster emulation, useful for testing) then run:
+
+```shell
+yacemu [PATH_TO_YOUR_ROM] turbo
+```
