start off by copying your local files to a remote machine using scp. You can choose one of the servers here
general command: scp <file_name_with_path> <kth_username>@<host>:<path_on_host>
example command: scp <file_name_with_path> [email protected]:~/Desktop/engineering-skills
now to check that your files are on the server by connecting via ssh
general command: ssh <kth_username>@<host>
example command: ssh [email protected]
