Part II: Working in a team coming soon

Hi! I'm Alex, creator of GitByBit.

This page is part of the interactive course about Git version control.

It's a one-of-a-kind course that is integrated into the VS Code code editor. Learning directly in VS Code lets you operate Git exactly as you would in real life, doing real jobs, writing real code.

In addition, the course has access to your actual terminal, so it can point out mistakes, suggest workarounds, etc.

The course is FREE, there are no Ads or other bullshit. There are optional premium add-ons you can purchase, mainly to support my work (regrettably, I have to eat every day), but that's totally up to you.
