 ## Preconditions
 
-- Successfully deployed OpenIM Server and its dependencies(mongo, kafka, redis, minio).
+- Ensure deployed OpenIM Server and its dependencies.
+  - Redis
+  - MongoDB
+  - Kafka
+  - MinIO
 - Expose the corresponding Services and ports of OpenIM Server.
 
 ## Deploy OpenIM Chat
 
-Chat depends on OpenIM Server, so you need to deploy OpenIM Server first.

 ### Modify ConfigMap
 
 You need to modify the `chat-config.yml` file to match your environment. Focus on the following fields:
 **discovery.yml**
 
 - `kubernetes.namespace`: default is `default`, you can change it to your namespace.
-- `enable`: set to `kubernetes`
-- `rpcService`: Every field value need to same to the corresponding service name. Such as `chat` value in same to `openim-chat-rpc-service.yml` service name.
-
-**log.yml**
-
-- `storageLocation`: log save path in container.
-- `isStdout`: output in kubectl log.
-- `isJson`: log format to JSON.
 
 **mongodb.yml**
 
 - `address`: set to your already mongodb address or mongo Service name and port in your deployed.
-- `username`: set to your mongodb username.
 - `database`: set to your mongodb database name.
-- `password`: **need to set to secret use base64 encode.**
-- `authSource`: set to your mongodb authSource, default is `openim_v3`.
+- `authSource`: et to your mongodb authSource. (authSource is specify the database name associated with the user's credentials, user need create in this database.)
 
 **redis.yml**
 
 - `address`: set to your already redis address or redis Service name and port in your deployed.
-- `password`: **need to set to secret use base64 encode.**
 
 **share.yml**
 
 - `openIM.apiURL`: modify to your already API address or use your `openim-api` service name and port
 - `openIM.adminUserID`: same to IM Server `imAdminUserID` field value.
-- `chatAdmin`: default is `chatAdmin`.
 
 ### 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:
 
-create a secret for redis password. You can create new file is `redis-secret.yml` or append contents to `chat-config.yml` use `---` split it.
+create a secret for redis password. You can update `redis-secret.yml`.
+
+you need update `redis-password` value to your redis password in base64.
 
 ```yaml
 apiVersion: v1
 kind: Secret
 metadata:
-  name: redis-secret
+  name: openim-redis-secret
 type: Opaque
 data:
-  redis-password: b3BlbklNMTIz # "openIM123" in base64
+  redis-password: b3BlbklNMTIz # you need update to your redis password in base64
 ```
 
 #### 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.
 
-OpenIM Server use prefix `IMENV_`, 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.
