Get started with Boost.

To set up the theme, you need:

  • A command line interface
  • Node.js

To install Node, go to Node.js, download it and follow the steps.

Files structure

Once you unzip the folder, you'll see the following file structure:

  • dist - production files
  • src - source files
    • assets
    • pages
    • templates - Nunjucks
  • .eleventy.js - Eleventy config
  • package.json - NPM dependencies
  • purgecss.config.js - PurgeCSS config

The dist folder contains the files you would upload to your web server to publish the site.


Open your terminal, make sure you are in the same directory of the unzipped theme, and run the following command to install all dependencies:

npm i

In the terminal, run the following command:

npm start

It compiles the source files, generates the site using Eleventy, and starts a local server.

Now go to http://localhost:8080 in your browser to see the site.

Front matter

You can add metadata in your template front matter:

layout: base
title: Home
description: Boost is a clean and accessible theme for Bootstrap.
permalink: /
  • Layout: the template used to wrap the content.
  • Title: page title.
  • Description: meta description.
  • Permalink: allows remapping your template's URI.


Once your site is ready to publish, run the following command:

npm run optim

It generates the site from scratch, formats the HTML, removes unused CSS, and compresses the images' size.
