Setup GitHub

1. Create GitHub Account

1. Go to https://github.com/.
2. Click Sign up in the top-right corner.
3. Enter your email address and click Continue.
4. Create a strong password and click Continue.
5. Choose a username (this will be your public identity on GitHub).
6. Follow the prompts to verify your account (you may need to solve a puzzle or enter a code sent to your email).
7. Choose your plan (the free plan is sufficient for most users).
8. Complete the setup by answering a few questions (optional) and click Complete setup.

2. Verify Your Email Address

1. Check your email inbox for a message from GitHub.
2. Click the verification link in the email to activate your account.

3. Set Up Your Profile

1. Click your profile icon in the top-right and select Your profile.
2. Click Edit profile to add your name, bio, location, and profile picture.
3. Save your changes.

4. Generate SSH Key

• When working with Git and GitHub, it’s a good idea to set up SSH keys for secure authentication.

• SSH keys are a pair of cryptographic keys that can be used to authenticate to GitHub without needing to enter your username and password every time.

• In your terminal, run:

  # Generate a new SSH key
  # -C is optional for email association with your GitHub account
  ssh-keygen -t rsa -C "your-email@example.com"
  

• This will create two files:

  File	Description
  ~/.ssh/id_rsa	Your private key (keep this secret)
  ~/.ssh/id_rsa.pub	Your public key (can be shared)

  # Example output
  $ ssh-keygen -t rsa -C "your-email@example.com"
  Generating public/private rsa key pair.
  Enter file in which to save the key (/root/.ssh/id_rsa): 
  Enter passphrase (empty for no passphrase): 
  Enter same passphrase again: 
  Your identification has been saved in /root/.ssh/id_rsa
  Your public key has been saved in /root/.ssh/id_rsa.pub <<< <<< <<< This is the key you need
  The key fingerprint is:
  SHA256:47MfTsMWlEN8PYpSGvYWlLd4u4fE4njqHrs53+oxEZM your-email@example.com
  The key`s randomart image is:
  +---[RSA 3072]----+
  |         oo. .   |
  |        o.=oo o  |
  |       . =E* o . |
  |        o.=++    |
  |        Sooo .   |
  |       . o.o+    |
  |        +oOo o   |
  |        oXo*o .  |
  |       oOO*...   |
  +----[SHA256]-----+
  

• Press Enter to accept the default file location and do not set a passphrase or you will be prompted to enter it each time you use the key.

5. Add your SSH to ssh-agent

• If you are using Windows, make sure you have Git Bash installed.
• If you are using Linux, make sure you have the ssh-agent package installed.
• If you are using macOS, you can use the built-in ssh-agent.
• Open Terminal and run:

  eval "$(ssh-agent -s)"
  ssh-add ~/.ssh/id_rsa
  

6. Add your SSH to GitHub

1. Copy your public key to your clipboard:

   pbcopy < ~/.ssh/id_rsa.pub  # macOS
   cat ~/.ssh/id_rsa.pub       # Linux/Windows, then copy manually
   

2. Go to GitHub site > Settings > SSH and GPG keys > New SSH key.
3. Paste your key, give it a title, and save.

7. Test Your Setup

• Run the following command to test your SSH connection:

  ssh -T git@github.com
  

• You should see a message like:

  Hi <username>! You've successfully authenticated, but GitHub does not provide shell access.
