+# Postmortem Bot Helm Chart
+
+This Helm chart deploys the Postmortem Automation Bot to your Kubernetes cluster, including both the webhook server and Discord bot.
+
+## Prerequisites
+
+- Kubernetes cluster (1.19+)
+- Helm 3.x
+- Docker image built and pushed to container registry
+
+## Installation
+
+### Quick Install
+
+```bash
+helm install postmortem-bot ./helm/postmortem-bot
+```
+
+### Install with Custom Values
+
+```bash
+helm install postmortem-bot ./helm/postmortem-bot \
+  --set webhook.image.repository=ghcr.io/techops-services/postmortem-automation \
+  --set webhook.image.tag=v1.0.0 \
+  --set discordbot.image.repository=ghcr.io/techops-services/postmortem-automation \
+  --set discordbot.image.tag=v1.0.0
+```
+
+### Install with Values File
+
+Create a `custom-values.yaml`:
+
+```yaml
+webhook:
+  enabled: true
+  replicaCount: 2
+  image:
+    repository: ghcr.io/techops-services/postmortem-automation
+    tag: v1.0.0
+  env:
+    - name: PAGERDUTY_API_KEY
+      valueFrom:
+        secretKeyRef:
+          name: postmortem-secrets
+          key: pagerduty-api-key
+    - name: DISCORD_WEBHOOK_URL
+      valueFrom:
+        secretKeyRef:
+          name: postmortem-secrets
+          key: discord-webhook-url
+
+discordbot:
+  enabled: true
+  replicaCount: 1
+  image:
+    repository: ghcr.io/techops-services/postmortem-automation
+    tag: v1.0.0
+  env:
+    - name: DISCORD_BOT_TOKEN
+      valueFrom:
+        secretKeyRef:
+          name: postmortem-secrets
+          key: discord-bot-token
+```
+
+Then install:
+
+```bash
+helm install postmortem-bot ./helm/postmortem-bot -f custom-values.yaml
+```
+

+
+## Creating Secrets
+
+Before deploying, create a Kubernetes secret with your credentials:
+
+```bash
+kubectl create secret generic postmortem-secrets \
+  --from-literal=pagerduty-api-key=YOUR_PAGERDUTY_KEY \
+  --from-literal=discord-webhook-url=YOUR_DISCORD_WEBHOOK \
+  --from-literal=discord-bot-token=YOUR_DISCORD_BOT_TOKEN \
+  --from-literal=google-drive-folder-id=YOUR_FOLDER_ID
+```
+
+## Upgrading
+
+```bash
+helm upgrade postmortem-bot ./helm/postmortem-bot -f custom-values.yaml
+```
+
+## Uninstalling
+
+```bash
+helm uninstall postmortem-bot
+```
+
+## Examples
+
+### Deploy Only Webhook Server
+
+```bash
+helm install postmortem-bot ./helm/postmortem-bot \
+  --set discordbot.enabled=false
+```
+
+### Deploy Only Discord Bot
+
+```bash
+helm install postmortem-bot ./helm/postmortem-bot \
+  --set webhook.enabled=false
+```
+
+### Scale Webhook Replicas
+
+```bash
+helm upgrade postmortem-bot ./helm/postmortem-bot \
+  --set webhook.replicaCount=3
+```
