+
+As the first step GitLab needs to be able to recognize you. We will use the most secured method: key-based authentication.
+
+You need to do it just ones (and repated if you change\crash\lost your laptop).<br>
+- Open terminal (command line)
+- Type `ssh-keygen -t ed25519 -C firstname.lastname@uni.lu`
+- Accept the suggested filename and directory (press Enter):<br>

+- Press Enter without entering the passphrase. <br>
+
+A public and private key are generated and stored in specific location on your laptop. You need to add the public key to your GitLab account.<br>
+- Copy the contents of your public key file. You can do this manually or<br>
+    - macOS: `tr -d '\n' < ~/.ssh/id_ed25519.pub | pbcopy`
+    - Windows: `cat ~/.ssh/id_ed25519.pub | clip`
+- Now let's move to GitLab https://gitlab.lcsb.uni.lu/
+
+
+
+# Key-based authentification
+- On the top bar, in the top right corner, select your avatar.
+- Select **Preferences**.
+- On the left sidebar, select **SSH Keys**.
+- In the **Key** box, paste the copied public key. Make sure it starts with ssh-ed25519 and finishes with your e-mail.
+- In the **Title** box, type a description, like *Work Laptop*.<br>
