 Documentation and Architecture for the openmcp-project.
 
+## Getting Started
+
+This site is built with [Docusaurus 3](https://docusaurus.io/).
+
+### 🚧 Prerequisites
+
+Make sure that you have installed the following tools on your local machine:
+
+- [Node.js](https://nodejs.org/en/download/) version 18.0 or above
+
+### 🧑‍💻 Local Development
+
+```sh
+# Install the latest packages.
+$ npm install
+
+# Start the development server.
+$ npm start
+```
+
+The local development server should start and open up a browser window. Most changes are reflected live without having to restart the server or reload the website.
+
+Changes to the documentation must be done via pull requests. A GitHub Actions [workflow](.github/workflows/test-deploy.yml) will check if the website can be built.
+
+### 🌍 Deployment
+
+Deployment is done using a GitHub Actions [workflow](.github/workflows/deploy.yml) when there are new commits on the `main` branch.
