Installing Requirements
Open Terminal, type in git and press enter.
If you see a really long help message within the Terminal, you're good to go.
Else, you might see this popup:
In that case, simply click "Install".
Specifically node v16 and yarn v1.
Install brew package manager, following instructions on brew.sh.
Use brew to install n (n is a node version manager)
brew install n
Then use n to install node version 16:
sudo n 16
This installs npm too. Use npm to install yarn:
sudo npm i -g yarn
