This should be the first video for all "github tutorial" searches.

One of the best introductory git videos on YT. Explains fundamentals, not just "type this, then this"

I might be a bit late, but this is a great video so I had to leave a comment. It is by far the best one I've seen on Git, carefully explaining basic concepts while also making it practical. Excellent work, David! Thank you for sharing it with us.

Commit == snapshot!!!! For some reason every other intro video skips this! It was a huge hole in my understanding. Thank you so much!

One of the best intros i have ever seen

[lapidations]

You got that awesome "audiobook voice" that works really well with the video! Great introduction, thanks a lot!

This is the first time I saw that git workflow graph, and I like how you keep referring back to it, showing how different git commands are reflected in the flow of information on the graph. It helped me to visualize what I am doing when I use git add and git commit.

[jackmaxwell]

the best video on git that I've found! Thanks a lot for your hard work!

[robertivanov]

You don't just show and share your knowledge, but you also show that teaching is an art as well!!! Thank you!

I've binge watching Git concept videos for the past 5 days. This is by far the best video of this topic !!

[ericmohler]

Excellent tutorial. The graphical representation of all three areas as you progress through a series of experiments is invaluable.
Thank you.

[heshammahmoud]

This is by far the best introduction about Git.

You are a gifted presenter David Mahler. Make more content please. Stunning. Reminds me of the documentaries I used to watch as a kid. Very well done.

Holy crap!! This is the best video on git I have ever seen. This video should be mandatory for all developers.

Best pacing I've seen in a Git tutorial. Helped me tremendously, thank you!

[shareclipsave]

David, you have such a great tone and pace for teaching. I can push the video speed to 1.75 and still grasp everything. Hopefully you can find more time to do videos on other information technology topics.

SO impressed by your thoroughness and clarity. You are very articulate and well spoken, the diagrams illustrate your talking points extremely well, it's not overly complicated, you highlight items on the screen that you are speaking to, and you revisit new ideas/concepts regularly - all of which are extremely helpful for new learners. This is fantastic!

[ceciliocbaroperez]

Magnificent explanation. Thanks for sharing this material so well-structured and easy to follow!

[kennethyuman]

Simple, but not simpler. Clear both in content and voice. Excellent. Thanks, David.
