Please note that you’ll have to install vim or any file editor in order to edit your assembly files. If you want to install vim, simply run in a terminal :

sudo apt install vim

To start editing a file, write :

vim {your_file}

Then press “A” to start editing it. Once done, press “Escp” and type :wq (or :x) to close and save the file, thus getting back to the terminal.

⚠️For the purpose of this course, you’ll need to put the extension “.asm” at the end of your assembly files if you’re using NASM assembler, and “.s” if you’re using the GNU assembler.
