 We wanted to build an open and inclusive, easy to use developer portal that offers guidance and allows community contribution. To achieve this we have chosen [Docusaurus 2](https://v2.docusaurus.io/), a modern static website generator.
 
-# Installation
+## Installation
 
 To contribute to the Cardano developer portal you must first install it locally.
 
-## Requirements
+### Requirements
 
 - [Node.js](https://nodejs.org/en/download/) version >= 12.13.0 or above (which can be checked by running `node -v`). You can use [nvm](https://github.com/nvm-sh/nvm) for managing multiple Node versions on a single machine installed.
 - [Yarn](https://yarnpkg.com/en/) version >= 1.5 (which can be checked by running `yarn --version`). Yarn is a performant package manager for JavaScript and replaces the `npm` client. It is not strictly necessary but highly encouraged.
 - On macOS you also need Xcode and Command Line Tools.
 
-## Local development
+### Local development
+
 To get a local development environment clone the repository, navigate into the `developer-portal` folder, install dependencies and start the development server. Most changes are reflected live without having to restart the server. By default, a browser window will open at `http://localhost:3000`.

 The development mode will have minor features not working. Like for example, only blurry images in the responsive images on showcase and tools, search limitations, and some data has fake values because of performance reasons.

-## Production build
+### Production build
+
 ```sh
 yarn build
 ```
+
 Use this command instead of `yarn start` to generate static content into the build directory that can be served using any static contents hosting service.
 
 ## Project structure
 
+The portal is structured as follows. (See the [Project structure rundown](#project-structure-rundown) below for details)
