 You can use the container to clone the GitLab repository. To do that: 
 1. Create the directory where you would like to store the repository, for example: *C:\cppcourse*;
 2. Run the container to execute the git clone command:  
-`docker run  --rm  --name cpp  -v c:\cppcourse:/home/student/cppcourse -w /home/student/cppcourse cppcourse git clone https://baltig.infn.it/fc-courses/it/programming/cpp-mag-2024.git`

 3. As an alternative you can execute the git command interactively in the running container:  
 `docker run  -it --rm  --name cpp  -v c:\cppcourse:/home/student/cppcourse cppcourse`  
 and the commands inside the container:  
 `cd cppcourse`  
-`git clone https://baltig.infn.it/fc-courses/it/programming/cpp-mag-2024.git`  
+`git clone https://baltig.infn.it/fc-courses/it/programming/cpp-mag-2025.git`  
   
 To update the GitLab repository:
-1. `docker run  --rm  --name cpp  -v c:\cppcourse:/home/student/cppcourse -w /home/student/cppcourse/cpp-mag-2024 cppcourse git pull`
+1. `docker run  --rm  --name cpp  -v c:\cppcourse:/home/student/cppcourse -w /home/student/cppcourse/cpp-mag-2025 cppcourse git pull`
 2. Or use the `git pull` command inside a running container (in the local repository).
