Move kind development instructions to top of dev cluster instructions.

kind provides an easy way for people to get started with developing
Tekton. This change promotes kind to the top of the cluster getting
started instructions, and simplifies the setup with easy copy+paste
commands.

Keeps reference to tekton_in_kind.sh, but does not rely on it for the
core setup instructions since it installs multiple tekton components
besides pipelines.

+#### Using [KinD](https://kind.sigs.k8s.io/)
+
+[KinD](https://kind.sigs.k8s.io/) is a great tool for working with Kubernetes clusters locally. It is particularly useful to quickly test code against different cluster [configurations](https://kind.sigs.k8s.io/docs/user/quick-start/#advanced).
+
+1. Install [required tools](./DEVELOPMENT.md#install-tools) (note: may require a newer version of Go).
+2. Install [Docker](https://www.docker.com/get-started).
+3. Create cluster:
+   
+   ```sh
+   $ kind create cluster
+   ```
+
+4. Configure [ko](https://kind.sigs.k8s.io/):
+   
+   ```sh
+   $ export KO_DOCKER_REPO="kind.local"
+   $ export KIND_CLUSTER_NAME="kind"  # only needed if you used a custom name in the previous step
+   ```
+
+optional: As a convenience, the [Tekton plumbing project](https://github.com/tektoncd/plumbing) provides a script named ['tekton_in_kind.sh'](https://github.com/tektoncd/plumbing/tree/main/hack#tekton_in_kindsh) that leverages `kind` to create a cluster and install Tekton Pipeline, [Tekton Triggers](https://github.com/tektoncd/triggers) and [Tekton Dashboard](https://github.com/tektoncd/dashboard) components into it.

-### Standing up a K8s cluster with Tekton using the `kind` tool
-
-An alternative to standing up your own K8s cluster and installing Tekton using `ko` is by using the [kind](https://kind.sigs.k8s.io/) tool. It was designed to help create and run local Kubernetes clusters in Docker to assist in local development and testing.
-
-The [Tekton "plumbing" project](https://github.com/tektoncd/plumbing) provides a convenience script, named ['tekton_in_kind.sh'](https://github.com/tektoncd/plumbing/blob/main/hack/tekton_in_kind.sh), that leverages `kind` to create a cluster and then deploy Tekton Pipeline, [Tekton Triggers](https://github.com/tektoncd/triggers) and [Tekton Dashboard](https://github.com/tektoncd/dashboard) components into it.
-
-See Tekton Plumbing's [DEVELOPMENT.md](https://github.com/tektoncd/plumbing/blob/main/DEVELOPMENT.md) for more details on this and other helpful scripts and tools.
-
-#### Installation and prerequisites
-
-- Clone the [Tekton Plumbing](https://github.com/tektoncd/plumbing) repository which has the ['tekton_in_kind.sh'](https://github.com/tektoncd/plumbing/blob/main/hack/tekton_in_kind.sh) and other helpful scripts.
-- `kind`: Install using its ["quick start"](https://kind.sigs.k8s.io/docs/user/quick-start/) documentation.
-- `Docker`: `kind` also requires Docker to be installed and running locally. Use the [Get Docker](https://docs.docker.com/get-docker/) instructions.
-
-#### Create a cluster with Tekton components
-
-Change into the Tekton plumbing repository you cloned and invoke the script:
-
-```shell
-cd plumbing
-./hack/tekton_in_kind.sh
-```
-
-The script, after using `kind` to create the K8s cluster, uses `kubectl` to install the `latest` released versions of Tekton components. After successful completion, the script will have:
-
-- Created a K8s cluster named `tekton`
-- Created a `cluster-context` for `kubectl` named `'kind-tekton'` and set it as the `current-context`
-- Deployed the latest Tekton Pipeline, Trigger and Dashboard components
-- Made Tekton Dashboard available at `http://localhost:9097`
-
-After the Tekton components are installed using this script, you can than use the `ko` tool to build and apply your development changes to the cluster for testing.
-
-##### Using a different cluster name and Tekton versions
-
-You can also specify a different cluster name and released versions of components you want installed:
-
-```shell
-# Script usage:
-tekton_in_kind.sh [-c cluster-name -p pipeline-version -t triggers-version -d dashboard-version]"
-```
-
-#### Delete the cluster
-
-If you wish to delete the cluster that the script created, use the following command:
-
-```shell
-# Delete the cluster using the default name
-kind delete cluster --name tekton
-```
-
-> **Note**: Be sure to set a `kubectl` context, as its unset as a side-effect of the delete (i.e., `kubectl config use-context`*`<context-name>`*).
