📚 Open Source Contribution (Day 1)

🔐 1. Generating an SSH Key for GitHub

SSH keys provide a secure way to authenticate with GitHub without repeatedly entering credentials.

Steps to set up an SSH key:

1. 
   Generate a new key:
   

   ssh-keygen -t ed25519 -C "[email protected]"  

1. 
   Save in the default location (press Enter).
   


2. 
   Start the SSH agent:
   

   eval "$(ssh-agent -s)"  

1. 
   Add the key to the agent:
   

   ssh-add ~/.ssh/id_ed25519  

1. 
   Copy the public key:
   

   cat ~/.ssh/id_ed25519.pub  

1. 
   Add it to GitHub:
   
   
   
   
   • Go to Settings → SSH and GPG Keys → New SSH Key
     
   
   
   • Paste the key and save.

• 
  Then, contribute by fixing errors, improving content, or coding.
  


• Common in open-source: Engage with the tool before enhancing it.
  

🆚 6. Free Software vs. Open Source

✅ Both allow code access and modification.
