Git Internals - Creating a Repo From Scratch

In order to deeply understand how git works, we will create a repository, but this time — build it from scratch.

We won’t use git init, git add or git commit which will enable us to get a better hands-on understanding in the process.
I have also posted two blog posts about git internals that cover the same topics:

this is gold
please continue with this content
(merge, rebase, reset, remote repo's, how the comparison between files is working, detached HEAD, what was the number :) ....)

This is too good. There is no other video currently that explains these concepts in such a detailed yet refreshing way. Please keep doing these videos. Thanks a lot

Almost in tears watching this unfold.. so good.
Will recommend to others

As many have already stated, this series is brilliant. Thank you! Git is intensity powerful and ubiquitous but, with all of its weird and unique terminology, it can be hard to fully understand what's going on and to have confidence in my commands. This series is a huge help. Even just knowing exactly where to check for the changes I've made is a big confidence boost.

If you create more videos in this format, my one bit of feedback for improvement would be to put a simple highlight square around either the terminal or the notes to show which side of the screen we should move our attention to. I watched most of this video concentrated solely on the terminal and didn't realise the notes had been updated with the pointers, etc.

But really, great job. Thank you for your effort 👍🏼🙏🏼

Pure gold. You are an amazing guru! "Brief channel is very 'AWESOME' !" :))

Absolutely BRILLIANT! Thank you so much! I've already shared it and am impatiently looking forward to the next episodes about merge, rebase, etc...

Your videos on Git are awesome. Such a simple explanation. Thanks for making these videos.

[piyushpasari]

This is super @Brief. Please help putting more to this. Great to have someone actually putting effort on something that is ignored by all.

[avimishra]

Why does he not have a billion subs, the content is fire dude . And what was the meaning of 100644 by the way?

[teji_]

Dude just turned 4 git commands (git init add commit branch) into 5 pages of notes🤯.
Felt like a linked list and pointers video more than git 😂
Awesome content❤

[ck.hodophile]

Wow!!!! I really appreciate the work.

It is really insightful, Keep the good work.

[bertjanbakker]

Excellent tutorial. I particularly like the style and the fact that you anticipate what questions the viewer might have. It's really useful to learn this, also when you just use git with 'porcelain' commands. For future videos it would e.g. be nice to explain what goes on when rebasing is done.

We need more videos in this git series, this were amazing
