After installing dependencies, add your source files to the src folder.
MJML files inside src / templates will be output as HTML in the dist folder. So it can be
statically served to be viewed in your favorite browser.
A cool folder to have is src/partials where you store your reusable files, since they're not
outputed to HTML.
After this initial setup, you can run npm run dev and your default browser should pop up, where
you can visualize your beaultiful email templates. As if emails could be beaultiful in any way...
Happy development!
