Install Git on Windows

Section 1: Installing Git for Windows

Visit https://git-scm.com/download/win and click on the first link: “Click here to download”.

Git Install for Windows

Open the file that was downloaded.
Choose yes to allow the Git installation on your PC.
Go through the installation and choose the default options.
For this step, we will choose the last option to give us extra commands to use.
For the rest of the installation, choose the default options.
Uncheck “View Release Notes” because we do not need it.

Section 2: Testing the Git installation

Once the installation is completed, open cmd.

In the search bar, type cmd and choose Command Prompt.
In the cmd window, type git --version. You should see Git version 2.27.0 or greater.
Note: If you get the following error:
Then, you need to add the PATH of Git into the Environment Variables.
In the cmd window, type “where git”:
Copy the first line and add it to the environment variables.
To open the environment variables in the search bar, type environment variables and choose “Edit the system environment variables”.
Choose Environment Variables.
In the System Variables, choose Path, then select the Edit Button.
Choose New, then Paste the Git location that you copied from the cmd window.
Close the cmd window, then open it one more time and type git --version to make sure that Git installed successfully.

Section 3: First-time Git setup

First of all, if you encounter any problems in this section, please read the official GitHub tutorial first, which can solve most of your problems. https://docs.github.com/en/authentication/connecting-to-github-with-ssh
Open PowerShell or Git Bash. If you don’t know what a terminal is, check out the tutorial What’s the Terminal?
The first thing you should do when you install Git is set your username and email address. This is important because every Git commit uses this information, and it’s immutably baked into the commits you start creating:
```
$ git config --global user.name "<username>"
$ git config --global user.email <email>
```
Note: replace <username> to your GitHub username, and <email> to the email address you used to register GitHub.
If you want to know more about the Git config command, you can see here: https://git-scm.com/book/en/v2/Getting-Started-First-Time-Git-Setup.
Please read this tutorial to generate SSH keys. Print the public key, then please select and copy the output.
```
$ cat ~/.ssh/id_<algorithm>.pub
```
Please replace <algorithm> with a specific algorithm, such as rsa, ecdsa, or ed25519. It depends on what algorithm you used to generate the SSH key.
Open the GitHub website. In the upper-right corner of any GitHub page, click your profile photo, then click Settings.
Then select the “SSH and GPG keys” section along the left-hand side. From there, click the “New SSH key” button.
In the “Title” field, add a descriptive label for the new key. For example, if you’re using a personal Mac, you might call this key “Personal MacBook Air”.
Paste the contents of the public-key file you coped in this section step 3 into the “Key” field and click “Add key”.
If prompted, confirm your GitHub password.

To test your SSH connection, enter the following in your terminal:

$ ssh -T git@github.com
# You may see a warning like this:
The authenticity of host 'github.com (IP ADDRESS)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
Are you sure you want to continue connecting (yes/no)?

Verify that the fingerprint in the message you see matches GitHub’s SSH key fingerprints. If it does, then type yes and press enter:
```
Hi your_GitHub_username! You've successfully authenticated, but GitHub does not provide shell access.
```
Verify that the resulting message contains your GitHub username. If you receive a “permission denied” message, see “Error: Permission denied (publickey)”.
