+# ipfs
+
+> A public IPFS node & gateway.
+> [ipfs.kretschmann.io](https://ipfs.kretschmann.io)
+
+[![Build Status](https://flat.badgen.net/travis/kremalicious/ipfs?icon=travis)](https://travis-ci.com/kremalicious/ipfs)
+
+This repo holds a simple React app built with [Next.js](https://nextjs.org) serving as the frontpage of [ipfs.kretschmann.io](https://ipfs.kretschmann.io) from where you can add files to IPFS via drag and drop.
+

+
+- [Development](#development)
+- [Production](#production)
+- [Deployment](#deployment)
+
+---
+
+## Development
+
+```bash
+npm i
+npm start
+```
+
+Will start a live-reloading local server, reachable under [localhost:3000](http://localhost:3000).
+
+## Production
+
+To create a production build, run from the root of the project:
+
+```bash
+npm run build
+```
+
+Outputs to `./public`.
+
+## Deployment
+
+Every branch is automatically deployed to [Now](https://zeit.co/now) with their GitHub integration. A link to a deployment will appear under each Pull Request.
+
+The latest deployment of the `master` branch is automatically aliased to `ipfs.kremalicious.now.sh`.
