 ## About
 [Lemmy](https://github.com/dessalines/lemmy) is similar to sites like [Reddit](https://reddit.com), [Lobste.rs](https://lobste.rs), [Raddle](https://raddle.me), or [Hacker News](https://news.ycombinator.com/): you subscribe to forums you're interested in, post links and discussions, then vote, and comment on them. Behind the scenes, it is very different; anyone can easily run a server, and all these servers are federated (think email), and connected to the same universe, called the [Fediverse](https://en.wikipedia.org/wiki/Fediverse).

 ## Install
 ### Docker
 Make sure you have both docker and docker-compose installed.
+
 ```
 git clone https://github.com/dessalines/lemmy
 cd lemmy
 ./docker_update.sh # This pulls the newest version, builds and runs it
 ```
+
 and goto http://localhost:8536
+### Kubernetes
+#### Requirements
+- Local or remote Kubernetes cluster, i.e. [`minikube`](https://kubernetes.io/docs/tasks/tools/install-minikube/)
+- [`kubectl`](https://kubernetes.io/docs/tasks/tools/install-kubectl/)
+- [`skaffold`](https://skaffold.dev/)
+#### Production
+```bash
+# Deploy the Traefik Ingress
+kubectl apply -f https://raw.githubusercontent.com/containous/traefik/v1.7/examples/k8s/traefik-rbac.yaml
+kubectl apply -f https://raw.githubusercontent.com/containous/traefik/v1.7/examples/k8s/traefik-ds.yaml
+# Replace ${IP} with your Ingress' IP
+echo "${IP} dev.lemmy.local" >> /etc/hosts
+```
+
+```bash
+skaffold run -p lemmy--prod
+```
+
+Now go to http://dev.lemmy.local.
+#### Development
+```bash
+skaffold dev -p lemmy--dev
+```
+
+Now go to http://localhost:4444. It automatically proxies to localhost, both if the cluster is local or remote; it also hot-reloads the UI and automatically recompiles and restarts the server.
