 ### Set the secret
 
 A Secret is an object that contains a small amount of sensitive data. Such as password and secret. Secret is similar to ConfigMaps.
 
-#### Example:
+#### Redis:
 
-create a secret for redis password. You can update `redis-secret.yml`.
-
-you need update `redis-password` value to your redis password in base64.
+Update the `redis-password` value in `redis-secret.yml` to your Redis password encoded in base64.
 
 ```yaml
 apiVersion: v1

-#### Usage:
-
-use secret in deployment file. If you apply the secret to IM Server, you need adapt the Env Name to config file and all toupper.
+#### Mongo:
 
-OpenIM Chat use prefix `CHATENV_`. Next adapt is the config file name. Like `redis.yml`. Such as `CHATENV_REDIS_PASSWORD` is mapped to `redis.yml` password filed in OpenIM Server.

-So, you need following configurations to set secret:
-
-- `MONGODB_USERNAME`
-- `MONGODB_PASSWORD`
-- `REDIS_PASSWORD`
-
-Apply the secret.

 ```shell
 kubectl apply -f redis-secret.yml -f mongo-secret.yml
