# so what we would like to accomplish is to initialize tailwind in a project
# install node modules to run tailwindcss
# run the command tailwind init to create the configuration file for tailwind
# pass in a input css file or the CLI will generate a default input.css file
# specify target files to watch
# the output css file that will be created 

# THINGS TO DO
# clean tailwind configuration, remove all the files regarding tailwind
# tailwind.config.js file, node modules, output file, input file containing tailwind base classes

# add the color palette feature with the color palette text file

# make the content list a findall file in folder list instead of the individual 

# update the content list again there should be a command for that

# create an update command that will update the content list, and the color palette if any
