.vimrc

" Vim looks for settings in ~/.vimrc (which is /root/.vimrc)
" However, if you edit /root/.vimrc, changes will be cleared when the container is restarted
" To make changes that apply in the next session and persist afterward, create or edit /mnt/learncli/.vimrc, which ~/.bashrc automatically copies to ~/.vimrc on startup
" To create, run cp /root/.vimrc /mnt/learncli/.vimrc
" While editing, to be able to test your changes, you can edit /root/.vimrc so that Vim can see the changes
" But copy /root/.vimrc to /mnt/learncli/.vimrc before exiting the container, or the changes will be lost
" This file is heavily documented, and some keybinds are near the bottom
" If you break some configuration while editing, just roll back to the original .vimrc
