+
+## Introduction
+
+This guide will help you set up a development environment for the Kubeflow Notebooks project.
+
+## Prerequisites
+
+- Go >= 1.22
+- Kubectl >= 1.22
+- A Kubernetes cluster (e.g. [kind](https://kind.sigs.k8s.io/))
+- Cert-manager installed in the cluster, see [cert-manager installation guide](https://cert-manager.io/docs/installation/#default-static-install)
+
+## Getting Started
+
+This project uses [Tilt](https://tilt.dev/) to manage the development environment. Tilt will watch for changes in the project and automatically rebuild the Docker image and redeploy the application in the **current Kubernetes context**.
+
+### In an existing cluster
+
+1. Make sure you have a Kubernetes cluster running and `kubectl` is configured to use it.
+2. Run the following command to start Tilt:
+
+```bash
+make -C devenv tilt-up
+```
+
+3. Hit `space` to open the Tilt dashboard in your browser and here you can see the logs and status of every resource deployed.
+
+### Using kind
+
+1. Create a kind cluster:
+
+```bash
+kind create cluster
+```
+
+2. Run the following command to start Tilt:
+
+```bash
+make -C devenv tilt-up
+```
+
+3. Hit `space` to open the Tilt dashboard in your browser and here you can see the logs and status of every resource deployed.
+
+## Teardown
+
+To stop Tilt and remove all resources created by it, run:
+
+```bash
+make -C devenv tilt-down
+```
+
+## Troubleshooting
+
+### "Build Failed: failed to dial gRPC: unable to upgrade to h2c, received 404"
+
+If you see the following error message when tilt builds the image, try setting `DOCKER_BUILDKIT=0`:
+
+```bash
+DOCKER_BUILDKIT=0 make -C devenv tilt-up
+```
