 # Digital Ocean Kubernetes Challenge
 
+Original Blogpost: [digitalocean.com/community/pages/kubernetes-challenge](https://www.digitalocean.com/community/pages/kubernetes-challenge#anchor--challenges)
+
 ## Project Description
 
 _Deploy a solution for configuring Kubernetes "from the inside"_
 Install Crossplane, which is like Terraform but you manage the infra from inside Kubernetes, not from outside. Crossplane is an open source Kubernetes add-on that enables platform teams to assemble infrastructure from multiple vendors, and expose higher level self-service APIs for application teams to consume, without having to write any code.
 
 ## Documentation
 
-can be found in `docs`
+I wrote about my journey with this challenge [here](docs/journey.md).
+_Maybe this becomes a blogpost eventually._
+
+In case you want try out what I build, follow the following steps.
+
+### How to set up
+
+This will create a baseline Kubernetes cluster at DigitalOcean.
+To deploy to your preferred region, add a `-var 'region=<YOUR_REGION>'` to step 3.
+
+1. `cd installation/`
+2. `terraform init`
+3. `TF_VAR_do_token=xyz terraform apply`
+
+After that, follow the documentation in the [Digital Ocean Provider](https://github.com/crossplane-contrib/provider-digitalocean).
+
+I chose the local `go run`, since no official docker image is available at the time of writing.
