+## Configuration options
+There are 2 ways 1Password Operator can talk to 1Password servers:
+- **Connect**: It uses the 1Password Connect API to access items in 1Password.
+- **Service Account**: It uses [1Password SDK](https://developer.1password.com/docs/sdks/) and [Service Account](https://developer.1password.com/docs/service-accounts) to access items in 1Password.

+## Kubernetes Operator Deployment with Service Account
+
+#### Create Kubernetes Secret for OP_SERVICE_ACCOUNT_TOKEN ####
+
+Create a Service Account token for the operator and save it as a Kubernetes Secret:
+
+```bash
+kubectl create secret generic onepassword-service-account-token --from-literal=token="$OP_SERVICE_ACCOUNT_TOKEN"
+```
+
+If you do not have a token for the operator, you can generate a token and save it to Kubernetes with the following command:
+
+```bash
+kubectl create secret generic onepassword-service-account-token --from-literal=token=$(op service-account create my-service-account --vault Dev:read_items --vault Test:read_items,write_items)
+```
+
+**Deploying the Operator**
+
+An sample Deployment yaml can be found at `/config/manager/manager.yaml`.
+To use Operator with Service Account, you need to set the `OP_SERVICE_ACCOUNT_TOKEN` environment variable in the `/config/manager/manager.yaml`. And remove `OP_CONNECT_TOKEN` and `OP_CONNECT_HOST` environment variables.
+
+To further configure the 1Password Kubernetes Operator the following Environment variables can be set in the operator yaml:
+
+- **OP_SERVICE_ACCOUNT_TOKEN** *(required)*: Specifies Service Account token within Kubernetes to access the 1Password items.
+- **WATCH_NAMESPACE:** *(default: watch all namespaces)*: Comma separated list of what Namespaces to watch for changes.
+- **POLLING_INTERVAL** *(default: 600)*: The number of seconds the 1Password Kubernetes Operator will wait before checking for updates from 1Password.
+- **AUTO_RESTART** (default: false): If set to true, the operator will restart any deployment using a secret from 1Password. This can be overwritten by namespace, deployment, or individual secret. More details on AUTO_RESTART can be found in the ["Configuring Automatic Rolling Restarts of Deployments"](#configuring-automatic-rolling-restarts-of-deployments) section.
+
+You can also set the logging level by setting `--zap-log-level` as an arg on the containers to either `debug`, `info` or `error`. (Note: the default value is `debug`.)
+
+Example:
+```yaml
+.
+.
+.
+containers:
+      - command:
+        - /manager
+        args:
+        - --leader-elect
+        - --zap-log-level=info
+        image: 1password/onepassword-operator:latest
+.
+.
+.
+```
+To deploy the operator, simply run the following command:
+
+```shell
+make deploy
+```
+
+**Undeploy Operator**
+
+```
+make undeploy
+```
+
 ## Usage
 
 To create a Kubernetes Secret from a 1Password item, create a yaml file with the following
