+# ESP32 Code
+
+If you would like to edit the code, feel free to edit `esp32.c`
+Feel free to change any options in the Makefile to help it work for your system.
+For example, where the Arduino libraries are held, the connecting baud rate, etc.
+Should work by default in most distributions.
+
+## Installing Dependencies
+
+To install the dependencies for the board, use the `make install-deps` command.
+
+You will also need to manually install the following packages/libraries:
+
+* `pyserial`, a Python library
+  * `pip install pyserial`
+* `tmux` and `screen` for serial viewing
+  * `apt install tmux screen`
+  * `pacman -S tmux screen`
+  * etc.
+* `arduino-cli` from your package manager
+
+## Compiling The Code
+
+To compile the source file, run the following command: `make`
+
+## Upload the code
+
+If you would like to upload the code to a connected device, use the `make upload` command.
+
+## Troubleshooting
+
+If you recieve an error about the `serial` package is not found, use the following command to install Python's serialization library:
+
+```bash
+$ pip install pyserial
