+<https://cloud.google.com/sdk/docs/install>
+
+- do a gcloud init and set it up to connect your GCP project
+- Edit the terraform.tfvars file to have your API key and Project ID
+
+```sh
+terraform plan
+terraform apply
+terraform output kubeconfig | grep -v EOT > ~/anthos.kubeconfig
+cd ~
+export KUBECONFIG=~/anthos.kubeconfig
+```
+
+- Install kubectl if you don't have it already
+
+<https://kubernetes.io/docs/tasks/tools/>
+
+- Validate the cluster is working
+
+```sh
+kubectl get nodes
+kubectl get pods
+kubectl patch storageclass local-shared -p '{"metadata":{"annotations":{"storageclass.kubernetes.io/is-default-class": "true"}}}'
+```
+
+- Install Helm if you don't have it already
+
+<https://helm.sh/docs/intro/install/>
+
+```sh
+git clone https://github.com/open-webui/open-webui/
+cd open-webui
+helm package ./kubernetes/helm/
+helm install ollama-webui ./open-webui-1.0.0.tgz --set webui.ingress.enabled=true
+kubectl get ingress open-webui
+```
+
+- You may need to wait a while for the ingress to be ready, just wait until the Address field has an IP address in it.
+
+- Open a web browser and go to that IP address, using normal http (no https): <http://IPADDRESSFROMLASTSTEP>
+
+- It may say no route to upstream while the webui is starting up, just keep refreshing until it works
+
+- Go to settings->Connections edit the ollama url and remove the /api at the end
+
+- click the little reload button next to the ollama url
+
+- Wait for it to pop up that it connected to ollama
+
+- Now go to the Settings->Models
+
+- Type `gemma:2b` into the "Pull a model from Ollama.com" box and click the download button
+
+- Wait for it to say the model has been successfully downloaded. This will take a while, even after it says 100%.
+
+- Close Settings
+
+- Choose gemma:2b from the models drop down
+
+- Type a prompt and see if it works
