+## k3s in docker
+
+k3s is the lightweight Kubernetes distribution by Rancher: [rancher/k3s](https://github.com/rancher/k3s)
+This repository is basically [zeerorg/k3s-in-docker](https://github.com/zeerorg/k3s-in-docker) reimplemented in Golang... just because I didn't have time to learn Rust.
+Also I've added some functionality.
+
+## Requirements
+
+- docker
+
+## Install
+
+Grab a release from the [release tab](https://github.com/iwilltry42/k3d-go/releases).
+
+or...

+## Build
+
+1. Clone this repo, e.g. via `go get -u github.com/iwilltry42/k3d-go/releases`
+2. Inside the repo run
+   - `make bootstrap` to install build tools and then `make build` to build for your current system
+   - `go install` to install it to your `GOPATH`
+   - `make build-cross` to build for all systems
+
+## Usage
+
+Check out what you can do via `k3d help`
+
+Example Workflow: Create a new cluster and use it with `kubectl`
+
+1. `k3d create` to create a new single-node cluster (docker container)
+2. `export KUBECONFIG=$(k3d get-kubeconfig)` to make `kubectl` to use the kubeconfig for that cluster
+3. execute some commands like `kubectl get pods --all-namespaces`
+4. `k3d delete` to delete the default cluster
