Configure Git

Before using Git, set your name and email:

git config --global user.name "Thirdy Gayares"
git config --global user.email "gayaresthird@gmail.com"

Create a Repository

You can create a new Git repository (repo) in your project directory.

Create a Directory
```
  mkdir myRepository
```

Navigate to your project folder:
```
  cd myRepository
```

Initialize the Git repository:

git init

Create File

Git Status

This will show you the changes in your working directory, such as new files or modified files.

Add Files to Staging Area

git add .

Commit Changes

Once the files are staged, you can commit them. A commit is like saving a snapshot of your project at that point.

git commit -m "Initial commit with project files"

Check Commit History

You can see your commit history with:

git log

Set Up Github Repository

Push to a Remote Repository

You can push your changes.

Add a remote repository:

git remote add origin https://github.com/Thirdy-Lecture/Github_Push_Example_2.git

Push changes to the remote repository:

git push -u origin master

How to resolve this issue ?

Go to https://github.com/settings/tokens

Choose classic

Check The Repo and Set note and Expiration then click generate token

Copy and paste the token key

git push -u origin master
Username for 'https://github.com': thirdgyayares
Password for 'https://thirdgayares@github.com': <Paste your Personal Access Token here>

Set up Credential Caching

If you don’t want to enter your token every time, you can cache your credentials using:

git config --global credential.helper cache

This will save your credentials for a while.

Alternatively, you can permanently store your credentials by using:

git config --global credential.helper store

This way, Git will store the credentials in a file, and you won’t be prompted for them again.

Check the repository on your Github
