-#### SCSS Foundation

-Usage for Open edX and others:
+**Usage with no theme:**
 
-**index.scss**
+The Paragon CSS Foundation offers a collection of fundamental styles, encompassing padding, typography, and sizing.
+When applied, these styles contribute to the creation of a straightforward and neat appearance for your application.
+
+To integrate these foundational styles into your project, include the following import:
 
 ```
-// ... Any custom SCSS variables should be defined here
-@import '~@openedx/paragon/scss/core/core.scss';
+@use "@openedx/paragon/dist/core.min.css";
 ```
 
-Usage on with `@edx/brand`:
+**Usage with a theme:**
+
+In addition to the basic styles, you can provide a theme layer that includes styles for colors, shadows, backgrounds
+and transparency of elements. This allows you to visually represent a specific theme in your application.
 
-**index.scss**
+To apply these theme-specific styles, include the following import:
 
 ```
-@import '~@edx/brand/paragon/fonts.scss';
-@import '~@edx/brand/paragon/variables.scss';
-@import '~@openedx/paragon/scss/core/core.scss';
-@import '~@edx/brand/paragon/overrides.scss';
+@use "@openedx/paragon/dist/core.min.css";
+@use "@my-brand/light.min.css";
 ```
 
-Note that including fonts will affect performance.  In some applications may choose not to load the custom font to keep it highly performant.
+**CDN links:**
+
+Alternative style integration is available when using CDN links:
+
+```
+@import url("https://cdn.jsdelivr.net/npm/@my-brand/core.min.css");
+@import url("https://cdn.jsdelivr.net/npm/@my-brand/light.min.css");
+```
 
 ## Paragon CLI
 
 The Paragon CLI (Command Line Interface) is a tool that provides various utility commands to automate actions within the Open edX environment.
 
 ### Available Commands
 
-- `paragon install-theme [theme]`: Installs the specific @edx/brand package.
+- `paragon install-theme`: Install a [brand package](https://github.com/openedx/brand-openedx).
+- `paragon migrate-to-openedx-scope`: Migrate from "@edx/paragon" to "@openedx/paragon".
+- `paragon build-tokens`: Build Paragon's design tokens.
+- `paragon replace-variables`: Replace SCSS variables usages or definitions to CSS variables and vice versa in `.scss` files.
+- `paragon build-scss`: Compile Paragon's core and themes SCSS into CSS.
 
 Use `paragon help` to see more information.

+## Design Tokens
+
+Design tokens are all the values needed to build and maintain a design system — spacing, color, typography, object styles, etc. They can represent anything defined by the design: color as an RGB value, opacity as a number, spacing as a REM value. They are used instead of hard-coded values to provide flexibility and uniformity across the application.
+
+By defining style properties as tokens, we can transform the styles into various implementations compatible with different platforms or formats as our use cases expand (e.g., transforming tokens to CSS variables, CSS utility classes, etc.).
+
+### Theming with design tokens
+
+Paragon uses [style-dictionary](https://github.com/amzn/style-dictionary) to build design tokens into CSS variables that are included in the package. Read more in [design tokens README](tokens/README.md).
+
+#### Compiling CSS from design tokens for Paragon contributions (in this repo)
+1. **`npm install`.** Install dependencies, including `style-dictionary`.
+2. Make changes to design token(s).
+3. **`npm run build-scss`.** Transforms the tokens to CSS variables and CSS utility classes, and generates `core.css` and `light.css` output files.
+    - `light.css`. CSS variable definitions for colors in the light theme variant.
+    - `core.css`. Contains the majority of Paragon/Bootstrap foundational styles for layout, components, etc. Consumes CSS variables defined by `light.css`.
+4. Test changes locally (e.g., running the documentation website, the example MFE app, etc.).
+5. Ensure changes to `core.css` and `light.css` are committed & released to NPM (which also "releases" them on versioned public CDNs for NPM packages).
+6. Consuming applications would inject the `core.css` and `light.css` theme files into their applications via a mechanism similar to https://github.com/openedx/frontend-platform/pull/440 (ideally pulling from a public CDN for NPM packages, but falling back to locally installed copies, if needed).
+
+#### Compiling CSS from design tokens for `@edx/brand` theme authors (in `@edx/brand` repos)
+1. **`npm install`.** Install dependencies, including `@openedx/paragon`.
+2. Create tokens that will override Paragon's default tokens (matching same JSON schema).
+3. **`npm run build-scss`.** This `@edx/brand` repo will have a new NPM script that utilizes a new CLI exported by `@openedx/paragon` which exposes the `build-tokens.js` script (or possibly another if we end up needing one for the brand packages to run specifically, TBD) for `@edx/brand` consumers.
+    - The intent of running this command is to effectively deep merge the tokens defined in Paragon's default tokens with the override tokens defined by `@edx/brand`, generating its own `core.css` and `light.css` output files (exact output files still a TBD) containing CSS variable overrides based on the token overrides.
+5. Ensure any changes to the generated `core.css` and `light.css` files are committed & released to NPM (which also "releases" them on versioned public CDNs for NPM packages).
+    - _Note: It is a bit unclear still in the above linked implementation POC for `@edx/frontend-platform` how it would integrate with `@edx/brand` in this way. Open to suggestions/feedback/ideas here._
