 To set up Dex, we would require to modify our litmusportal-server a bit in order to communicate with Dex. This will be achieved by adding some environment variables
 
-- `OIDC_ISSUER`: The place where the Dex OIDC lives, i.e `NODE_IP:32000`
+- `OIDC_ISSUER`: The place where the Dex OIDC is hosted, i.e `NODE_IP:32000` or `https://dex.yourdomain.com`
 - `DEX_ENABLED`: This variable enables dex features in the litmusportal-server
-- `CALLBACK_URL`: This is the url that will be called back after user completes thier OAuth, this will be the litmusportal-frontend service
+- `DEX_OAUTH_CALLBACK_URL`: This is the url that will be called back after user completes thier OAuth, this will be the litmusportal-frontend service
 
 Set your variables using 
 
 ```bash
-kubectl set env deployment/litmusportal-server -n litmus --containers="auth-server" DEX_SERVER="true", OIDC_ISSUER=<REPLACE_NODE_IP>:32000, CALLBACK_URL=<REPLACE_litmusportal_frontend_Service>
+kubectl set env deployment/litmusportal-server -n litmus --containers="auth-server" DEX_ENABLED=true OIDC_ISSUER=<REPLACE_NODE_IP>:32000 DEX_OAUTH_CALLBACK_URL=https://<REPLACE_FRONTEND_URL>/auth/dex/callback
 ```
 Your litmusportal-server pod will be restarted and Dex features will be enabled!
 
 ### Verifying if OAuth2 is enabled
 
+Run the following command to check the env variables of the `auth-server`
+
+```bash
+kubectl describe deployment litmusportal-server -n litmus auth-server
+```
+
+Under `auth-server`, verify if the `DEX_ENABLED` variables are set
+
+<span style={{color: 'green'}}><b>Expected Output</b></span>
+
+```bash
+   auth-server:
+    Image:       litmuschaos/litmusportal-auth-server:ci
+    Ports:       3000/TCP, 3030/TCP

+    Environment:
+      STRICT_PASSWORD_POLICY:  false
