re the lesson 1 intro "If you have more experience with programming and using git, and Github, you’re going to want to head over to the course’s repo and clone the project. From there, you can switch between different branches for the starting and ending code for each lesson. For example, in the next lesson (lesson two) you can check out L2-start or L2-end for the starting and ending code, respectively."

Enlarge on that, there and in the proposed README, with an example:

git clone https://github.com/Code-Pop/Intro-to-Vue-3.git --branch L3-start --single-branch --depth 1 lesson3

Or whatever git syntax is proper.

Consider adding, to the V M course lesson with the vscode howto material on using vscode's integrated git stuff. Note that one of the V M course lessons has an oops moment: "Whoa! looks like that just nuked all we've coded, but not to worry: thank goodness for git versioning, just undo the change". However the lesson did not speak to using the needed versioning prior.

Just installed node, vue and vue-cli switched to project directory expecting to start to code but ended like this:

git clone https://github.com/Code-Pop/Intro-to-Vue-3.git
cd Intro-to-Vue-3.git

~/workspace/vue3/Intro-to-Vue-3$ vue-cli-service serve

I'm missing a package.json, so you can clone the repo and still stuck with something that doesn't work. A simple README would be welcome so we can read it, execute what is needed and be done with it and follow the course.
