+# Pre-Registration Module
+
+## Install
+
+* Make sure your prereg UI domain name is set in [global configmap](../../cluster/global_configmap.yaml.sample)
+* Make sure this domain points to the public load balancer as PreReg UI is exposed to public.
+* Install
+  ```sh
+  ./install.sh
+  ```
+
+## Uninstall
+
+```sh
+./delete.sh
+```
+
+## Test
+On a browser open  `https://<prereg ui domain>/pre-registration-ui/`. Example `https://prereg.sandbox.xyz.net/pre-registration-ui`.  Follow the instructions.  You may use [sample documents](samples/) to upload during pre-registration. 
+
+## Rate Control Using Envoyfilter
+
+- Using Envoyfilter one can limit the rate of http requests coming in to a resource. Reference: [Istio Policty Enforcement](https://istio.io/latest/docs/tasks/policy-enforcement/rate-limit/#local-rate-limit) and [Rate Limit Filter](https://www.envoyproxy.io/docs/envoy/latest/configuration/http/http_filters/local_rate_limit_filter).
+- Edit the envoyfilter [here](./rate-control-envoyfilter.yaml)
+  - Edit these values in the envoyfilter accordingly.
+    ```
+    token_bucket:
+      max_tokens: <preferred same as tokens_per_fill>
+      tokens_per_fill: <no of reqeust allowed in "fill_internal" ammount of time>
+      fill_interval: <minimum_50ms>
+    ```
+  - Edit the workload selector label properly, like;
+    ```
+    workloadSelector:
+      labels:
+        app.kubernetes.io/instance: <prereg-ui or prereg-application, etc>
+    ```
+- Apply the envoyfilter in the prereg namespace.
+  ```
+  kubectl apply -n prereg -f rate-control-envoyfilter.yaml
+  ```
