 These are just a few common configuration options. If you don't need them, you can read through our [config center instructions](https://github.com/openimsdk/open-im-server/blob/main/docs/contrib/environment.md).
 
 Render the required configuration via './scripts/init-config.sh 'or' make init '. It can be modified directly https://github.com/openimsdk/openim-docker/blob/main/scripts/install/environment.sh or set linux environment variables. For example, above `PASSWORD` and `USER`. The latter method works only on the current terminal

+## OpenIM Data Storage Architecture Guide
+
+### **II. OpenIM Default Data Storage Structure**
+
+**A. Overview**
+
+At the heart of OpenIM's data storage are the essential components: Kafka, MNT, MongoDB, MySQL, and Redis. Each serves a distinct purpose and requires specific configuration and data directories for optimal performance.
+
+**B. Directory Structure**
+
+```bash
+$ tree components/ -d -L 2
+components/
+├── kafka
+│   ├── config
+│   └── data
+├── mnt
+│   ├── config
+│   └── data
+├── mongodb
+│   └── data
+├── mysql
+│   └── data
+└── redis
+    ├── config
+    └── data
+```
+
+
+### III. Customizing OpenIM's Data Storage
+
+**A. Setting a Custom Directory**
+
+For organizations with specific storage directory requirements, OpenIM offers the flexibility to specify a custom directory. Follow these steps:
+
+1. Define your custom directory path by setting the `DATA_DIR` environment variable:
+
+```bash
+$ export DATA_DIR="/path/to/your/directory"
+```
+
+1. Refresh OpenIM's configuration to reflect this change:
+
+```bash
+$ make init
+```
+
+**Note:** This action will update the configuration to point to the directory you've specified.
+
+
+### IV. Docker Volume Storage: An Advanced Approach
+
+**A. Why Docker Volumes?**
+
+Docker volumes offer isolated storage solutions, optimizing data persistence and performance. When scaling services in Docker, using volumes ensures that data remains consistent and protected.
+
+**B. Using Docker Volumes with OpenIM**
+
+To launch OpenIM with Docker volume support, execute:
+
+```bash
+$ docker compose -f example/volume-all-server.yml up -d
+```
+
+With this setup, your OpenIM data is securely mounted onto Docker's volumes, providing added resilience and scalability.
+
+**C. Managing Docker Volumes**
+
+1. **Listing OpenIM Docker Volumes**
+
+Retrieve a list of Docker volumes associated with OpenIM using:
+
+```bash
+$ docker volume ls | grep open-im-server
+```
+
+1. **Removing Data**
+
+- For **locally mapped data**: Simply navigate to the appropriate directory and delete the desired files or folders.
+- For **Docker volume data**: If you wish to clear data from Docker volumes, employ the command below:
+
+```bash
+$ docker volume ls | grep open-im-server | awk '{print $2}' | xargs docker volume rm
+```
+
+**Warning:** This action will permanently erase the data. Always ensure you have backups before proceeding.
