" summary

Explains why Git works by walking through concrete mechanics: SHA‑1 hashes, the commit DAG, staging area versus working directory, and commits as immutable objects with parents; how branches/tags/HEAD are just 40‑char pointers; collaboration via fetch, push and fast‑forward merge; conflict flow (edit markers, add, commit); cherry‑pick to apply single commits; rebase and interactive rebase (pick/squash to rewrite local history) and warnings about git pull, reset and checkout. Recommends GUI viewers (gitx/gitk) to visualize the tree.
