+# NextJS Slack Clone Helm Chart
+
+This Helm chart deploys the NextJS Slack Clone application to a Kubernetes cluster.
+
+## Prerequisites
+
+- Kubernetes 1.19+
+- Helm 3.2.0+
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```bash
+# For deployments without private registry
+helm install my-release ./helm/nextjs-slack-clone
+
+# For deployments with private registry authentication
+helm install my-release ./helm/nextjs-slack-clone \
+  --set registry.username=your-username \
+  --set registry.password=your-password
+```
+
+## Configuration
+
+The following table lists the configurable parameters of the NextJS Slack Clone chart and their default values.
+
+### Private Registry Authentication
+
+This Helm chart supports pulling images from a private Docker registry with basic authentication. Configure the following values:
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `registry.url` | URL of the private registry | `registry.mattiaswiberg.com` |
+| `registry.username` | Username for registry authentication | `""` |
+| `registry.password` | Password for registry authentication | `""` |
+
+For security reasons, it's recommended to provide the registry credentials during installation rather than storing them in the values.yaml file.
+
+| Parameter | Description | Default |
+| --------- | ----------- | ------- |
+| `replicaCount` | Number of replicas | `1` |
+| `image.repository` | Image repository | `nextjs-slack-clone` |
+| `image.tag` | Image tag | `latest` |
+| `image.pullPolicy` | Image pull policy | `IfNotPresent` |
+| `service.type` | Kubernetes service type | `ClusterIP` |
+| `service.port` | Kubernetes service port | `80` |
+| `service.targetPort` | Application port | `3000` |
+| `ingress.enabled` | Enable ingress | `false` |
+| `resources` | CPU/Memory resource requests/limits | `{}` |
+| `env.NEXT_PUBLIC_SUPABASE_URL` | Supabase URL | `""` |
+| `env.NEXT_PUBLIC_SUPABASE_ANON_KEY` | Supabase anonymous key | `""` |
+
+## Setting Environment Variables
+
+To set the required Supabase environment variables, use the `--set` flag when installing the chart:
+
+```bash
+helm install my-release ./helm/nextjs-slack-clone \
+  --set env.NEXT_PUBLIC_SUPABASE_URL=your-supabase-url \
+  --set env.NEXT_PUBLIC_SUPABASE_ANON_KEY=your-supabase-anon-key
+```
+
+Alternatively, you can create a custom values file with your environment variables:
+
+```yaml
+# my-values.yaml
+env:
+  NEXT_PUBLIC_SUPABASE_URL: your-supabase-url
+  NEXT_PUBLIC_SUPABASE_ANON_KEY: your-supabase-anon-key
+```
+
+And then install the chart using:
+
+```bash
+helm install my-release ./helm/nextjs-slack-clone -f my-values.yaml
+```
+
+## Enabling Ingress
+
+To enable the ingress and configure a hostname:
+
+```bash
+helm install my-release ./helm/nextjs-slack-clone \
+  --set ingress.enabled=true \
+  --set ingress.hosts[0].host=your-hostname.com \
+  --set ingress.hosts[0].paths[0].path=/ \
+  --set ingress.hosts[0].paths[0].pathType=Prefix
+```
