+# Git Commands Guide
+
+## Getting Started with Git
+
+### 1. Installing Git
+
+Before you begin, ensure Git is installed on your machine. You can download it from [git-scm.com](https://git-scm.com/).
+
+### 2. Check Git Installation
+
+To verify that Git is installed, run:
+
+```bash
+git --version
+```
+
+### 3. Configure Git User Information
+
+Set up your name and email address, which will be used for your commits:
+
+```bash
+git config --global user.name "Your Name"
+git config --global user.email "your.email@example.com"
+```
+
+## Configuring Git to Use a Custom SSH Key
+
+If you need to use a specific SSH key for your Git operations, you can configure Git as follows:
+
+```bash
+git config --add --local core.sshCommand 'ssh -i <PATH_TO_SSH_KEY>'
+```
+
+For Clone With Custom SSH Key Use:
+```bash
+git -c core.sshCommand="ssh -i <key-path>" clone host:repo 
+```
+
+
+*Replace `<PATH_TO_SSH_KEY>` with the actual path to your SSH key file.*
+
+## Creating and Managing a Local Git Repository
+
+### 1. Initialize a Git Repository
+
+Start by creating a new Git repository in your local project directory:
+
+```bash
+git init -b main
+```
+
+*The `-b main` flag sets the default branch name to "main".*
+
+### 2. Add Files and Commit Changes
+
+Next, stage all your files and create your initial commit:
+
+```bash
+git add -A
+git commit -m "Initial Commit"
+```
+
+*The `git add -A` command stages all changes, while the `git commit` command records those changes with a descriptive message.*
+
+### 3. Connect to a Remote Repository
+
+Now, link your local repository to a remote GitHub repository:
+
+```bash
+git remote add origin <Repo-Link>
+```
+
+*Replace `<Repo-Link>` with the URL of your GitHub repository.*
+
+### 4. Push Changes to GitHub
+
+Finally, push your initial commit to the remote repository:
+
+```bash
+git push origin main
+```
+
+## Common Git Commands for Beginners
+
+### 1. Check the Status of Your Repository
+
+To see which changes are staged, unstaged, or untracked:
+
+```bash
+git status
+```
+
+### 2. View Commit History
+
+To view the commit history of your repository:
+
+```bash
+git log
+```
+
+*You can press `q` to exit the log view.*
+
+### 3. Viewing Changes
+
+To see changes made to files before staging them:
+
+```bash
+git diff
+```
+
+### 4. Staging Individual Files
+
+If you want to stage specific files instead of all changes:
+
+```bash
+git add <filename>
+```
+
+*Replace `<filename>` with the name of the file you wish to stage.*
+
+### 5. Undoing Changes
+
+To unstage a file that you added by mistake:
+
+```bash
+git reset <filename>
+```
+
+To discard changes in a file and revert it to the last committed state:
+
+```bash
+git checkout -- <filename>
+```
+
+### 6. Cloning a Repository
+
+If you want to create a copy of an existing remote repository:
+
+```bash
+git clone <Repo-Link>
+```
+
+*Replace `<Repo-Link>` with the URL of the repository you want to clone.*
+
+### 7. Creating a New Branch
+
+To create a new branch for development:
+
+```bash
+git checkout -b <branch-name>
+```
+
+*Replace `<branch-name>` with your desired branch name.*
+
+### 8. Merging Branches
+
+To merge changes from another branch into your current branch:
+
+```bash
+git merge <branch-name>
+```
