 This repository contains the contents for the Research Software Support platform.
 
 This platform uses the [NEBULA framework](https://github.com/esciencecenter-digital-skills/NEBULA).
+
+For elaborate setup instructions and other documentation, see the [NEBULA documentation](https://github.com/esciencecenter-digital-skills/NEBULA-docs)
+
+
+# Quick local setup
+
+## Content directory/repository
+
+To use NEBULA to build the content in this repository locally, you will need to clone this repository and the NEBULA repository:
+
+```bash
+git clone [email protected]:esciencecenter-digital-skills/research-software-support.git
+git clone [email protected]:esciencecenter-digital-skills/NEBULA.git
+```
+
+## Link to the content repository
+
+To make sure that NEBULA knows where to find the content, we create the following environment variable:
+
+```bash
+export CONTENT_PATH="~/path/to/your/content/repository"
+```
+
+## Install dependencies
+
+Install the dependencies using the [node package manager](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm):
+
+```bash
+# node package manager
+npm install
+```
+
+## Local development build
+
+Start the development server on `http://localhost:3000`:
+
+```bash
+# node package manager
+npm run dev
+```
+
+Now you can open a browser and navigate to `http://localhost:3000/research-software-support`
