+External Secrets Operator integration with [Delinea Secret Server](https://docs.delinea.com/online-help/secret-server/start.htm).
+
+### Creating a SecretStore
+
+You need a username, password and a fully qualified Secret Server tenant URL to authenticate
+i.e. `https://yourTenantName.secretservercloud.com`.
+
+Both username and password can be specified either directly in your `SecretStore` yaml config, or by referencing a kubernetes secret.
+
+To acquire a username and password, refer to the  Secret Server [user management](https://docs.delinea.com/online-help/secret-server/users/creating-users/index.htm) documentation.
+
+Both `username` and `password` can either be specified directly via the `value` field (example below)
+>spec.provider.secretserver.username.value: "yourusername"<br />
+spec.provider.secretserver.password.value: "yourpassword" <br />
+
+Or you can reference a kubernetes secret (password example below).
+
+```yaml
+apiVersion: external-secrets.io/v1beta1
+kind: SecretStore
+metadata:
+  name: secret-server-store
+spec:
+  provider:
+    secretserver:
+      serverURL: "https://yourtenantname.secretservercloud.com"
+      username:
+        value: "yourusername"
+      password:
+        secretRef:
+          name: <NAME_OF_K8S_SECRET>
+          key: <KEY_IN_K8S_SECRET>
+```
+
+### Referencing Secrets
+
+Secrets may be referenced by secret ID or secret name.
+>Please note if using the secret name
+the name field must not contain spaces or control characters.<br />
+If multiple secrets are found, *`only the first found secret will be returned`*.
+
+Please note: `Retrieving a specific version of a secret is not yet supported.`
+
+Note that because all Secret Server secrets are JSON objects, you must specify the `remoteRef.property`
+in your ExternalSecret configuration.<br />
+You can access nested values or arrays using [gjson syntax](https://github.com/tidwall/gjson/blob/master/SYNTAX.md).
+
+```yaml
+apiVersion: external-secrets.io/v1beta1
+kind: ExternalSecret
+metadata:
+    name: secret-server-external-secret
+spec:
+    refreshInterval: 15s
+    secretStoreRef:
+        kind: SecretStore
+        name: secret-server-store
+    data:
+      - secretKey: SecretServerValue #<SECRET_VALUE_RETURNED_HERE>
+        remoteRef:
+          key: "52622" #<SECRET_ID>
+          property: "array.0.value" #<GJSON_PROPERTY> * an empty property will return the entire secret
+```
+
+### Preparing your secret
+You can either retrieve your entire secret or you can use a JSON formatted string
+stored in your secret located at Items[0].ItemValue to retrieve a specific value.<br />
+See example JSON secret below.
+
+### Examples
+Using the json formatted secret below:
+
+- Lookup a single top level property using secret ID.
+
+>spec.data.remoteRef.key = 52622 (id of the secret)<br />
+spec.data.remoteRef.property = "user" (Items.0.ItemValue user attribute)<br />
+returns: marktwain@hannibal.com
+
+- Lookup a nested property using secret name.
+
+>spec.data.remoteRef.key = "external-secret-testing" (name of the secret)<br />
+spec.data.remoteRef.property = "books.1" (Items.0.ItemValue books.1 attribute)<br />
+returns: huckleberryFinn
+
+- Lookup by secret ID (*secret name will work as well*) and return the entire secret.
+
+>spec.data.remoteRef.key = "52622" (id of the secret)<br />
+spec.data.remoteRef.property = "" <br />
+returns: The entire secret in JSON format as displayed below
+
+
+```JSON
+{
+  "Name": "external-secret-testing",
+  "FolderID": 73,
+  "ID": 52622,
