Then process the css using the tachyons-cli

$ npm i -g tachyons-cli
$ tachyons path/to/css-file.css > dist/t.css

Using the css

CDN

The easiest and most simple way to use the css is to use the cdn hosted version. Include it in the head of your html with:

<link rel="stylesheet" href="http://unpkg.com/tachyons-background-position@1.0.0/css/tachyons-background-position.min.css" />
Locally

The built css is located in the css directory. It contains an unminified and minified version. You can either cut and paste that css or link to it directly in your html.

<link rel="stylesheet" href="path/to/module/css/tachyons-background-position">

Development

The source css files can be found in the src directory. Running $ npm start will process the source css and place the built css in the css directory.
