+# Starting teraslice using helm and helmfile
+
+## Prerequisites
+
+The following dependencies are required to successfully deploy a basic instance of Teraslice and interact with its API. The examples provided use Homebrew (brew) and Node.js's (npm) for installation.
+
+- Docker
+- [Helm](https://helm.sh/docs/intro/install/)
+    - `brew install helm`
+- [helmfile](https://formulae.brew.sh/formula/helmfile)
+    - `brew install helmfile`
+- [Kubectl](https://kubernetes.io/docs/reference/kubectl/)
+    - `brew install kubectl`
+- [Kind](https://kind.sigs.k8s.io/) - Kubernetes in Docker
+    - `brew install kind`
+- [curl](https://formulae.brew.sh/formula/curl) - Command-line tool for making HTTP requests
+    - `brew install curl`
+- [teraslice-cli](https://www.npmjs.com/package/teraslice-cli) - A CLI tool for managing Teraslice
+    - `npm install -g teraslice-cli`
+
+### Initial Setup
+
+First you're going to want to be in the correct directory. Starting in the top level of the teraslice directory:
+
+```bash
+cd ./examples/helm
+```
+
+### Step 1: Creating a Kind Cluster
+
+Create a single node Kubernetes cluster by running the following command:
+
+```bash
+kind create cluster --config kindConfig.yaml
+```
+
+### Step 2: Building the Teraslice Docker Image
+
+Build the teraslice docker image using the following command. Ensure the image is tagged correctly to match the intended version `dev-nodev22.9.0` in this example:
+
+```bash
+docker build -t ghcr.io/terascope/teraslice:dev-nodev22.9.0 ../../.
+```
+
+### Step 3: Loading the Teraslice Docker Image into the Kind Cluster
+
+Load the Teraslice Docker image, built above, into the Kind cluster's control plane:
+
+```bash
+kind load docker-image --name k8s-env ghcr.io/terascope/teraslice:dev-nodev22.9.0
+```
+
+### Step 4: Verifying the Image Load
+
+Confirm that the teraslice image has been successfully loaded into the cluster. The following command lists the images available in the clusters control plane:
+
+```bash
+docker exec -it k8s-env-control-plane crictl images
+```
+
+### Step 5: Verifying the Kubernetes Resource Configuration
+
+Generate a preview of the Kubernetes resources that will be deployed. This step ensures that the `helmfile` is configured correctly:
+
+```bash
+helmfile diff
+```
+
+### Step 6: Deploying Resources
+
+Lastly if there were no errors with the `diff` command, deploy teraslice and opensearch into the cluster by running:
+
+```bash
+helmfile sync
+```
+
+### Step 7: Deploying Assets
+
+The example job requires the `standard-assets` and `elasticsearch-assets` to be available in the cluster for successful execution. Use the `teraslice-cli` tool to deploy these assets:
+
+```bash
+teraslice-cli assets deploy localhost terascope/standard-assets
+```
+
+```bash
+teraslice-cli assets deploy localhost terascope/elasticsearch-assets
+```
+
+### Step 8: Submitting and Starting a Test Job
+
+This example job generates `10,000` records and writes them to an Opensearch index named `random-data-1`. Submit the job to the Teraslice API using the following command:
+
+```bash
+curl -XPOST 'localhost:5678/v1/jobs' -H "Content-Type: application/json" -d '{
+    "name": "data-to-es",
+    "lifecycle": "once",
+    "workers": 1,
+    "assets": [
+        "standard",
+        "elasticsearch"
+    ],
+    "operations": [
+        {
+            "_op": "data_generator",
+            "size": 10000
+        },
+        {
+            "_op": "elasticsearch_bulk",
+            "size": 10000,
+            "index": "random-data-1"
+        }
+    ]
+}'
+
+```
+
+### Step 9: Viewing results in opensearch
+
+Once the job completes, query Opensearch to verify that the documents have been written successfully. Use the following command to view the index information:
+
+```bash
+curl 'localhost:9200/_cat/indices?v&h=index,status,docs.count,docs.deleted,store.size,pri.store.size'
+```
+
+Results:
+
+```bash
+index                        status docs.count docs.deleted store.size pri.store.size
+teraslice__assets            open            2            0      2.8mb          2.8mb
+teraslice__state-2024.11     open            1            0     28.8kb         28.8kb
+teraslice__ex                open            1            0     49.1kb         49.1kb
+teraslice__jobs              open            1            0      5.6kb          5.6kb
+random-data-1                open        10000            0        7mb            7mb
+teraslice__analytics-2024.11 open            4            0     23.9kb         23.9kb
