 # TankControllerGUI
 A Python GUI for TankController running on the mocks provided by `Arduino CI`.
 
-## Build Process
+## Build Process (Mac/Linux) [Not up to date]
 Follow these steps
 * `python3 -m pip install wxPython pybind11`
-* `cd GUI`
+* `cd extras/mockUI`
 * ``filePath=`bundle exec which arduino_library_location.rb` ``
 * `export ARDUINO_CI=${filePath%/bin/*}/gems/arduino_ci-1.3.0/cpp/arduino`
 * `make clean`
 * `(mkdir -p build; cd build; make -f ../Makefile)`
 * `python3 TankController.py`
 
+## Build Process (Windows)
+Follow these steps
+* Install Ruby via https://rubyinstaller.org
+* Inside IDE terminal (Or equivalent Powershell terminal) 
+  * `cd extras/mockUI`
+  * `irb`
+  * `gem install bundler arduino_ci`
+  * `require 'arduino_ci'; puts Gem::Specification.find_by_name('arduino_ci').gem_dir`
+  * Copy the returned directory
+  * `exit`
+* Inside powershell terminal 
+  * `python3 -m pip install wxPython pybind11`
+  * `$env:ARDUINO_CI = "[INSERT DIRECTORY HERE]"`
+  * `echo $env:ARDUINO_CI` Should return the directory that was given earlier
+  * `pip install libTC`
+* Inside the MINGW64 terminal
+  * `make clean`
+  * If the make file fails, ensure you have make installed on the MINGW64 version of Git Bash
+  * `(mkdir -p build; cd build; make -f ../Makefile)`
+  * `python3 TankController.py`
+  * NOTE: As of right now, there will likely be an error like this: `"D:\Code\OpenSource\TankControllerMockUIRework\extras\mockUI\TankController.py", line 6, in <module>import libTC ModuleNotFoundError: No module named 'libTC'`
+    * This is because there are modules that cannot be found in libTC.cpp, for example, <Arduino.h> cannot be found and used in that file. No solution has been found as of yet.
+
+## Makefile Specs
 The `Makefile` provides for making the following:
 * `libtc.dylib` (on macOS) containing the following:
   * `Arduino CI` mocks (essentially the Arduino OS)
