 # GitGuardian NHI Helm Charts
 
+## Installation
+
+Add the repository to Helm with:
+
+```shell
+helm repo add gg-nhi https://gitguardian.github.io/nhi-explorer-helm-charts
+```
+
+Then install the explorer, with a values file (examples below):
+
+```shell
+helm upgrade explorer gg-nhi/nhi-explorer --install --values values.yml
+```
+
+An example values file that fetches from HashiCorp Vault:
+
+```yaml
+inventory:
+  # Run every 15 minutes
+  schedule: '*/15 * * * *'
+  config:
+    sources:
+      vault-secrets:
+        type: hashicorpvault
+        vault_address: "https://your-vault-address-here"
+        # Token configuration can be read from environment variables like so:
+        auth_token: "${HASHICORP_VAULT_TOKEN}"
+        fetch_all_versions: true
+        path: "secret/"
+
+# This needs to be created separately, and contain a `HASHICORP_VAULT_TOKEN` key with 
+# the token to use.
+envFrom:
+  - secretRef:
+      name: hashicorpvault-secrets
+```
+
+Other examples can be found in [charts/nhi-explorer/examples](charts/nhi-explorer/examples).
