+    cd memoryscope
+    # edit configuration, e.g. add api keys
+    vim memoryscope/core/config/demo_config_zh.yaml
+    ```
+
+2. Build Docker image
+    ```bash
+    sudo docker build --network=host -t memoryscope .
+    ```
+
+
+3. Launch Docker container
+    ```bash
+    sudo docker run -it --rm --net=host memoryscope
+    ```
+
+
+## II. Install with docker compose [Recommended]
+
+
+1. Clone the repository and edit settings
+    ```bash
+    # clone project
+    git clone https://github.com/modelscope/memoryscope
+    cd memoryscope
+    # edit configuration, e.g. add api keys
+    vim memoryscope/core/config/demo_config_zh.yaml
+    ```
+
+
+2. Edit `docker-compose.yml` to change environment variable.
+    ```
+    DASHSCOPE_API_KEY: "sk-0000000000"
+    ```
+
+3. Run `docker-compose up` to build and launch the memory-scope cli interface.
+
+
+## III. Install from PYPI [Linux only]
+
+1. Install from pypi:
+
+    ```bash
+    pip install memoryscope
+    ```
+
+
+2. test Chinese / Dashscope chat configuration:
+
+    ```bash
+    export DASHSCOPE_API_KEY="sk-0000000000"
+    memoryscope --config_path=memoryscope/core/config/demo_config_zh.yaml
+    ```
+
+3. test English / OpenAI chat configuration:
+
+    ```bash
+    export OPENAI_API_KEY="sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
+    python quick-start-demo.py --config_path=memoryscope/core/config/demo_config.yaml
+    ```
+
+
+## IV. Install from source [Linux only]
+
+1. Clone the repository and edit settings
+    ```bash
+    # clone project
+    git clone https://github.com/modelscope/memoryscope
+    cd memoryscope
+    # edit configuration, e.g. add api keys
+    vim memoryscope/core/config/demo_config_zh.yaml
+    ```
+
+2. Install 
+    ```bash
+    poetry install
+    ```
+
+3. Run Elasticsearch service, refer to [elasticsearch documents](https://www.elastic.co/guide/en/elasticsearch/reference/current/getting-started.html).
+The docker method is recommended:
+    ```
+    sudo docker run -p 9200:9200 \
+    -e "discovery.type=single-node" \
+    -e "xpack.security.enabled=false" \
+    -e "xpack.license.self_generated.type=trial" \
+    docker.elastic.co/elasticsearch/elasticsearch:8.13.2
+    ```
+
+4. Launch memoryscope, also refer to [cli documents](../examples/cli/README.md)
+    ```bash
+    pip install -r requirements.txt
+    export DASHSCOPE_API_KEY="sk-0000000000"
+    python quick-start-demo.py --config_path=memoryscope/core/config/demo_config_zh.yaml
+    ```

+# MemoryScope 安装指南
+
+## 一、使用 Docker 安装 [推荐]
+
+1. 克隆仓库并编辑配置
+    ```bash
+    # 克隆项目
+    git clone https://github.com/modelscope/memoryscope
+    cd memoryscope
+    # 编辑配置，例如添加 API 密钥
+    vim memoryscope/core/config/demo_config_zh.yaml
+    ```
+
+2. 构建 Docker 镜像
+    ```bash
+    sudo docker build --network=host -t memoryscope .
+    ```
+
+3. 启动 Docker 容器
+    ```bash
+    sudo docker run -it --rm --net=host memoryscope
+    ```
+
+
+## 二、使用 Docker Compose 安装 [推荐]
+
+1. 克隆仓库并编辑配置
+    ```bash
+    # 克隆项目
+    git clone https://github.com/modelscope/memoryscope
+    cd memoryscope
+    # 编辑配置，例如添加 API 密钥
+    vim memoryscope/core/config/demo_config_zh.yaml
+    ```
+
+2. 编辑 `docker-compose.yml` 文件以更改环境变量。
+    ```
+    DASHSCOPE_API_KEY: "sk-0000000000"
+    ```
+
+3. 运行 `docker-compose up` 命令来构建并启动 MemoryScope CLI 界面。
+
+
+## 三、通过 PYPI 安装 [仅限 Linux]
+
+1. 从 PyPI 安装：
+    ```bash
+    pip install memoryscope
+    ```
+
+2. 测试中文 / Dashscope 对话配置：
+    ```bash
+    export DASHSCOPE_API_KEY="sk-0000000000"
+    memoryscope --config_path=memoryscope/core/config/demo_config_zh.yaml
+    ```
+
+3. 测试英文 / OpenAI 对话配置：
+    ```bash
+    export OPENAI_API_KEY="sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
+    python quick-start-demo.py --config_path=memoryscope/core/config/demo_config.yaml
+    ```
+
+
+## 四、从源码安装 [仅限 Linux]
+
+1. 克隆仓库并编辑设置
+    ```bash
+    # 克隆项目
+    git clone https://github.com/modelscope/memoryscope
+    cd memoryscope
+    # 编辑配置，例如添加 API 密钥
+    vim memoryscope/core/config/demo_config_zh.yaml
+    ```
+
+2. 安装依赖
+    ```bash
+    poetry install
+    ```
+
+3. 运行 Elasticsearch 服务，参照 [Elasticsearch 文档](https://www.elastic.co/guide/cn/elasticsearch/reference/current/getting-started.html)。
+推荐使用 Docker 方法：
+    ```
+    sudo docker run -p 9200:9200 \
+    -e "discovery.type=single-node" \
+    -e "xpack.security.enabled=false" \
+    -e "xpack.license.self_generated.type=trial" \
+    docker.elastic.co/elasticsearch/elasticsearch:8.13.2
+    ```
+
+4. 启动 MemoryScope，同时参考 [CLI 文档](../examples/cli/README.md)
+    ```bash
+    pip install -r requirements.txt
+    export DASHSCOPE_API_KEY="sk-0000000000"
+    python quick-start-demo.py --config_path=memoryscope/core/config/demo_config_zh.yaml
