 # Getting started with LPSC project
 
+## Getting started with git
+
+### Managing SSH keys
+
+#### Generate an SSH key paie
+
+**For more details**, please consult the following link: [SSH Keys](https://gitedu.hesge.ch/-/user_settings/ssh_keys)
+
+If you do not have an existing SSH key pair, you can generate a new one:
+
+Run `ssh-keygen -t` command followed by the key type and an optional comment. This comment is included in the `.pub` file which is created. **In out case, we use the school's email address as a comment (e.g., <firstname.lastname>@hesge.ch)**.
+
+For instance, for ED25519:
+
+> ```sh
+> $ ssh-keygen -t ed25519 -C "<firstname.lastname>@hesge.ch"
+> ```
+
+You will have an output similar to the following which is displayed:
+
+> ```sh
+> Generating public/private ed25519 key pair.
+> Enter file in which to save the key (/home/user/.ssh/id_ed25519):
+> ```
+
+You then have to specify a passphrase:
+
+> ```sh
+> Enter passphrase (empty for no passphrase):
+> Enter same passphrase again:
+> ```
+
+A public and private key are generated. **Add the public SSH key to your GitLab account**.
+
+#### How to use the ssh key
+
+When you open a terminal, before using the git command, you have to add your private key (e.g., `id_ed25519`) with the following command:
+
+> ```sh
+> ssh-add ~/.ssh/<your_private_key>
+> ```
+
+You then have to enter your passphrase:
+
+> ```sh
+> Enter passphrase for /home/user/.ssh/id_ed25519_hesge:
+> ```
+
+### Git configuration
+
+Set the name and the email address which will be attached to your commits and tags.
+
+> ```sh
+> $ git config --global user.name "Your name"
+> $ git config --global user.email "your-email@hesge.ch"
+> ```
+
+Enable some colorisation of Git output.
+
+> ```sh
+> $ git config --global color.ui auto
+> ```
+
+### Clone the git repository
+
+The first step is to clone the directory and its submodules.
+
+> ```sh
+> $ git clone ssh://git@ssh.hesge.ch:10572/cores/lpsc.git
+> $ cd lpsc
+> $ git submodule update --init --recursive
+> ```
+
+### Pull with submodules
+If you have already cloned the repository, you can pull changes and update the submodules in a single command like this:
+
+> ```sh
+> $ git pull --recurse-submodules
+> ```
+
+Or from a specific branch (e.g., main) like this:
+
+> ```sh
+> $ git pull origin main --recurse-submodules
+> ```
+
+#### Update submodules after pulling
+
+In case you already pulled the main repository and forgot to include submodule update, you can manually update the submodules using:
+
+> ```sh
+> $ git sub modules update --recursive --remote
+> ```
+
