Installing Git

Before you can start using Git, you need to install it on your computer. You can download and install Git from the official website: Git官网.

Creating a Repository

A repository is a collection of files and directories that Git can track changes to. To create a new repository, navigate to the directory where you want to create the repository and run the following command:

git init

Making Changes

Once you have a repository, you can start making changes to the files. You can create new files, modify existing files, or delete files.

Committing Changes

After making changes, you need to commit them to the repository. A commit is a snapshot of your changes. To commit your changes, run the following command:

git commit -m "Your commit message"

Branching

Git uses branches to allow multiple developers to work on the same repository without interfering with each other's work. To create a new branch, run the following command:

git checkout -b new-branch

Merging

Once you're done working on a branch, you can merge it back into the main branch. To merge a branch, run the following command:

git merge new-branch

Tags

Tags are used to mark specific points in the repository history. To create a tag, run the following command:

git tag -a v1.0 -m "Initial release"
