Saying this lemme share the big picture about Git - just the concept: * Git is just a software installed on your machine (usually comes with Linux and Mac 😭). When you run git init, it creates a hidden .git folder in your project root that stores everything - commits, history, branches, tags, etc... U can see it making hidden files visible. * Git is a graph of commits(directed acyclic graph) , where every commit is a node pointing back to the previous commit(node), so your project history becomes a chain/graph of nodes (commits) * A branch is just a movable pointer to a commit; creating a branch means creating another pointer at the same commit, and then each branch can evolve independently as new commits are added. * tag is also a fixed pointer to a commit, used to mark stable versions like v1.0, v2.0, releases, etc., and unlike branches, tags never move. .. Etc... So basically like : git = a graph of commit, branches = moving pointers on commits , tags = fixed pointers, and the .git folder is where the entire system lives.
