 - Babel - will allow us to use ESNext or possibly even TypeScript (although this could go against the lean requirement)
 - Storybook - allow viewing and testing of components (we have already used this elsewhere in TNA)
+
+#### Storybook
+
+Most widely supported open source frontend workshop for building UI components, constantly updated, also used by TDR
+
+#### ESNext JavaScript (not TypeScript)
+
+JavaScript over TypeScript to allow in-project compilation and possible tree-shaking without extra libraries
+
+#### Babel
+
+De facto JavaScript compiler and transpiler, allows us to use most up-to-date JavaScript for increased efficiency and cleaner source code
+
+#### SCSS
+
+Most mature CSS preprocessor, used in other TNA projects, huge support
+
+#### BEM
+
+Agreed CSS methodology within TNA
+
+#### Webpack
+
+Already used in many TNA projects, most mature offering although arguably not the fastest - we could consider changing in the future
+
+#### Nunjucks
+
+Used by GDS and made by Mozilla, Nunjucks is simple and expandable and allows us to use components in the GOV.UK prototype kit
+
+#### npm
+
+Used by many TNA projects and provides highly available package repository, de facto standard for JavaScript packages
+
+#### GitHub actions
+
+Free actions not relying on external services, used on some TNA projects but will allow us to have more of a CI/CD methodology
+
+#### Prettier
+
+Opinionated code formatter for (S)CSS, JavaScript, JSON and other file types, intended to reduce bikeshedding
+
+#### ESLint
+
+De facto linter for JavaScript to catch potential issues
+
+#### Stylelint
+
+Most widely supported and mature (S)CSS linter
+
+#### Jest
+
+Lightweight and fast testing library, support for Storybook, easy learning curve
+
+#### NVM
+
+Ensures all developers can work on the same version of NodeJS, reduces differences between development environments
+
+#### Chromatic.com
+
+Suggested by Storybook for visual regression testing

 ### Files
 
-- `_index.scss` - where you can add your [BEM](https://getbem.com/) SCSS styles for the component
+- `_index.scss` - Simply includes `@use "myComponent";` so we can include this directory within SASS and have it reference the styles in `[myComponent].scss`
+- `[myComponent].scss` - this file gets built as a standalone file as well as being included in all styles and is where you can add your [BEM](https://getbem.com/) SCSS styles for the component
 - `fixtures.json` - these are snapshots of the rendered component's HTML in different scenarios which can be used by other implementations to test against
 - `macro-options.json` - the options for the component which are rendered in the Design System as well as being copied in to the Storybook controls
 - `macro.njk` - the Nunjucks macro easily allows us to include components in the prototype kit and other applications such as the Design System

-# Technologies
-
-## Storybook
-
-Most widely supported open source frontend workshop for building UI components, constantly updated, also used by TDR
-
-## ESNext JavaScript (not TypeScript)
-
-JavaScript over TypeScript to allow in-project compilation and possible tree-shaking without extra libraries
-
-## Babel
-
-De facto JavaScript compiler and transpiler, allows us to use most up-to-date JavaScript for increased efficiency and cleaner source code
-
-## SCSS
-
-Most mature CSS preprocessor, used in other TNA projects, huge support
-
-## BEM
-
-Agreed CSS methodology within TNA
-
-## Webpack
-
-Already used in many TNA projects, most mature offering although arguably not the fastest - we could consider changing in the future
-
-## Nunjucks
-
-Used by GDS and made by Mozilla, Nunjucks is simple and expandable and allows us to use components in the GOV.UK prototype kit
-
-## npm
-
-Used by many TNA projects and provides highly available package repository, de facto standard for JavaScript packages
-
-## GitHub actions
-
-Free actions not relying on external services, used on some TNA projects but will allow us to have more of a CI/CD methodology
-
-## Prettier
-
-Opinionated code formatter for (S)CSS, JavaScript, JSON and other file types, intended to reduce bikeshedding
-
-## ESLint
-
-De facto linter for JavaScript to catch potential issues
-
-## Stylelint
-
-Most widely supported and mature (S)CSS linter
-
-## Jest
-
-Lightweight and fast testing library, support for Storybook, easy learning curve
-
-## NVM
-
-Ensures all developers can work on the same version of NodeJS, reduces differences between development environments
-
-## Chromatic.com
-
-Suggested by Storybook for visual regression testing

+
+## NPM
+
+Install the frontend package from NPM with:
+
+```sh
+npm install @nationalarchives/frontend
+```
+
+### CSS
+
+From here, you have access to include the SCSS files from the package so you can compile the package yourself:
+
+```css
+// Include all the styles
+@include("node_modules/@nationalarchives/frontend/nationalarchives/all");
+
+// ...or just include a single component
+@include("node_modules/@nationalarchives/frontend/nationalarchives/components/tabs");
+```
+
+...or you can copy any of the compiled CSS files into your distribution:
+
+- `node_modules/@nationalarchives/frontend/nationalarchives/all.css`
+- `node_modules/@nationalarchives/frontend/nationalarchives/all.css.map`
+- `node_modules/@nationalarchives/frontend/nationalarchives/components/tabs.css`
+- `node_modules/@nationalarchives/frontend/nationalarchives/components/tabs.css.map`
+
+### JavaScript
+
+```js
+// Import all the JavaScript
+import "node_modules/@nationalarchives/frontend/nationalarchives/all.mjs";
+
+// ...or import just the JavaScript for a single component
+import "node_modules/@nationalarchives/frontend/nationalarchives/components/tabs/tabs.mjs";
