+## Dashboard Installation
+
+On this page you can learn how to install the open-source Gimlet on any Kubernetes cluster.
+
+If you prefer to use our hosted SaaS platform, [sign up here](https://gimlet.io/signup) then skip ahead to [connect a Kubernetes cluster](#connect-your-cluster).
+
+### Prerequisites
+
+- A [Github.com](https://github.com) personal or organization account.
+- A Kubernetes cluster running on your laptop or on a cloud provider. We recommend using k3d on your laptop if you are evaluating Gimlet. It takes only a single command to start one, and it runs in a container.
+
+#### Launching k3d on your laptop - optional
+
+K3d is a lightweight Kubernetes cluster that runs in a container on your laptop. At Gimlet, we use k3d solely for our local needs and we recommend you do the same.
+
+Install k3d with:
+
+```
+curl -s https://raw.githubusercontent.com/k3d-io/k3d/main/install.sh | bash
+```
+
+Then launch a cluster:
+
+```
+k3d cluster create gimlet-cluster --k3s-arg "--disable=traefik@server:0"
+```
+
+Once your cluster is up, validate it with `kubectl get nodes`:
+
+```
+INFO[0000] Prep: Network

+INFO[0000] Created image volume k3d-gimlet-cluster-images

+k3d-gimlet-cluster-server-0   Ready    control-plane,master   11s   v1.26.4+k3s1
+```
 
-Gimlet is installable by a kubectl apply:
+### Install Gimlet with a oneliner
 
 ```
 kubectl apply -f https://raw.githubusercontent.com/gimlet-io/gimlet/main/deploy/gimlet.yaml
 ```
 
-or with a Helm chart:
+Then access it with port-forward on [http://127.0.0.1:9000](http://127.0.0.1:9000)
 
 ```
-helm template gimlet onechart/onechart -f fixtures/gimlet-helm-values.yaml -n default
+kubectl port-forward svc/gimlet 9000:9000
 ```
 
-## Documentation
+![](/admin-login.png)
+
+#### Admin password
+
+You can find the admin password in the logs:
+
+```
+$ kubectl logs deploy/gimlet | grep "Admin auth key"
+time="2023-07-14T14:28:59Z" level=info msg="Admin auth key: 1c04722af2e830c319e590xxxxxxxx" file="[dashboard.go:55]"
+```
+
+#### Alternative installation method
+
+We generate the Kubernetes manifests from a Helm chart. You can use this configuration directly with Helm if you prefer.
+
+```
+helm template gimlet onechart/onechart \
+  -f https://raw.githubusercontent.com/gimlet-io/gimlet/main/fixtures/gimlet-helm-values.yaml
+```
+
+For all Gimlet environment variables, see the [Gimlet configuration reference](/docs/gimlet-configuration-reference).
+
+### Basic configuration
+
+#### Connect your repositories
+
+To connect your git repositories to Gimlet, follow the on-screen guides.
+
+Important to note:
+
+- When you integrate with Github, you don't give access to any third party or the makers of Gimlet.
+- The integration allows for fine-grained permission grants. You can pick the repositories that you want to integrate with Gimlet.
+
+#### Connect your cluster
+
+Navigate to the "Environments" tab.
+
+Notice that Gimlet created a dummy environment for you. Normally you would call your environments staging or production, but this is a dummy environment, mine is called _Bold Grass_ 🙃.
