We recommend setting up the Semantic build workflow to support on-the-fly theming and customization, but it is not required.

To use the "ready-to-use" distribution version, which includes all components, simply link to dist/semantic.js and dist/semantic.css (or their minified counterparts) in your page.

<link rel="stylesheet" type="text/css" href="/dist/semantic.min.css">
<script src="/dist/semantic.min.js"></script>

You may also prefer to use individual components found in dist/components to reduce the libraries file size.

<link rel="stylesheet" type="text/css" href="/dist/components/icon.css">

Semantic is best used actively during development. We have included build tools for updating your site's theme as you work.

npm install
gulp

Running gulp for the first time will start the interactive set-up.

This helps you create two important files semantic.json which stores your folder set-up, and themes.config a central file for setting ui themes.

The install utility will also help you set-up which components you want to include in your packaged release, ignoring parts of Semantic you may not use.

Once set-up you can use these commands to maintain your project

gulp  // defaults to watch after install
gulp build // build all files from source
gulp clean // clears your dist folder
gulp watch // watch files
gulp install // re-runs install
gulp help // list all commands
