Run nvim with Lazyvim setup in a Docker container with data stored in $HOME per usual. Does not require any changes to main system.

# Build the container that includes nvim, python, node, luarocks, lazygit
./nvim.sh --build 

# Setup lazyvim in $HOME - customizations in core.lua will be copied over
./nvim.sh --setup

# Setup an alias
alias nvim=/path/to/nvim.sh
alias vi=nvim
