Porcelain and Plumbing

In Git, commands are divided into high-level ("porcelain") commands and low-level ("plumbing") commands. The porcelain commands are the ones that you will use most often as a developer to interact with your code. Some porcelain commands are:

git status
git add
git commit
git push
git pull
git log

Don't worry about what they do yet, we'll cover them in detail soon. Some examples of plumbing commands are:

git apply
git commit-tree
git hash-object

We'll focus on the high-level commands because that's what you use 99% of the time as a developer, but we'll dip down into the low-level commands occasionally to really understand how Git works.
