  Step 1: Basic Raspberry Pi Configuration

  We prepare the SD card (in this case, I’m using a 64 GB one). For that, we use Raspberry Pi Imager. Make sure to select the following options:

  In the hostname field, I make sure to set argentv.local (we’ll use it later, but you can choose any hostname you like).

  Make sure to configure the Wi-Fi credentials, language, and region. Leave SSH enabled so you can access the Raspberry Pi remotely later on:

  Click Install, and we’ll meet again in a few minutes 😉 […] Once the flashing process is done, insert the SD card into the Raspberry Pi. If you see the following screens, you’re on the right track:

  Prepare remote access to the RPI

  Next, we’ll try to access the Raspberry Pi remotely. Open your command console and type:

  ssh argentv.local

  You might see the following message:

  If that happens, try this:

  ssh-keygen -R argentv.local

  Once done, try again with ssh argentv.local, and this time you should see something like this:

  After typing yes, new certificates will be installed, and the SSH connection to the Raspberry Pi will be established.

  During the setup, my username was “rs”. Yours might differ — keep that in mind for the next steps.

  Since this is the very first boot after formatting the SD card, let’s run the following commands:

  sudo apt update && sudo apt upgrade –y

  Prepare to clone the GitHub Repo

   Now let’s clone the GitHub repository. Before that, we need to configure our SSH keys.

  If you already have SSH keys, skip this step

  ls -l ~/.ssh/id_ed25519 ~/.ssh/id_ed25519.pub 2>/dev/null || true

   Generate a new key (ED25519). Choose a helpful comment:

  ssh-keygen -t ed25519 -C "pi@argentv"

   Press Enter to accept the default path (~/.ssh/id_ed25519). You can leave the passphrase empty (just press Enter) or add one for better security.

  Show the public key (this one goes to GitHub)

  cat ~/.ssh/id_ed25519.pub

   (Optional) Load it into the SSH agent so you don’t have to enter your passphrase every time

  eval "$(ssh-agent -s)"
  ssh-add ~/.ssh/id_ed25519

   Copy that public key and add it to your GitHub account: GitHub → your avatar → Settings → SSH and GPG keys → New SSH key → paste the key.

  Test the connection with GitHub (it should greet you with your username)

  ssh -T git@github.com
