running file pug
# install pug globall sudo npm install pug --global #get to your folder and running this : pug -w ./ -o ./html -P
Here is what the above code is Doing:
1. pug is the command to run the pug compiler
2. -w is the watch flag, which tells pug to watch for changes to your files
3. ./ is the folder to watch
4. -o ./html is the output folder
5. -P tells pug to compile the files with the .pug extension
