+### Using K/V version 1
+
+By default, `vault-action` expects a K/V engine using [version 2](https://www.vaultproject.io/docs/secrets/kv/kv-v2.html).
+
+In order to work with a [v1 engine](https://www.vaultproject.io/docs/secrets/kv/kv-v1/), the `kv-version` parameter may be passed:
+
+```yaml
+with:
+    kv-version: 1
+```
+
+### Custom Engine Path
+
+When you enable the K/V Engine, by default it's placed at the path `secret`, so a secret named `ci` will be accessed from `secret/ci`. However, [if you enabled the secrets engine using a custom `path`](https://www.vaultproject.io/docs/commands/secrets/enable/#inlinecode--path-4), you
+can pass it as follows:
+
+```yaml
+with:
+    path: my-secrets
+    secrets: ci npmToken
+```
+
+This way, the `ci` secret in the example above will be retrieved from `my-secrets/ci`.
