Must have OS version up to at least 10.15.7, otherwise cannot work on Mac.

Install Python 3.8.10
- Go to: https://www.python.org/downloads/release/python-380/

Install pip

```
python3 -m pip install PACKAGE
```
Install Xcode
- For old OS users, sign up as a developer in Apple and download the proper version/ sign up here: https://developer.apple.com/download/all/?q=xcode
  - For 10.15.7 this is 12.4, otherwise, google your current OS and find the compatible version of Xcode.
- Activate its licence by opening terminal from your mac applications and run the line:
```
sudo xcodebuild -license
```
Install VSCode
- A comprehensive guide to downloading/installing VSCode can be found at: https://code.visualstudio.com/docs/languages/python
- Set up your working folder in VSCode to store your files and such.
- To check which version of Python you are using, type the following within the terminal:
```
python3 -v
```
- Press Command+Shift+P, select "Python:select Interpreter", and select "Python Version 3.8".
- Running the previous command in the terminal now should show python 3.8.10.
Ensure wheels are up to date
- Within the terminal of VScode, run:
```
python3 -m pip install --upgrade pip setuptools wheel
```
Download Numpy
- Within the terminal of VScode, run:
```
python3 -m pip install numpy
```
Download openCV
- Within the terminal of VScode, run:
```
python3 -m pip install opencv-contrib-python
```
- This could take about 30 min to an hour.
Check proper installation
- To ensure the package has installed correctly in a new python file within VScode, type:
```
import cv2
cv2.aruco. 
```
- While typing the second line and leaving the last period open, a large list of functions within the ArUco package should appear for use. Otherwise, try one of the Cvis files to see if it recognizes the functions.
