+**You can run openmdlb-exporter from docker, or install and run directly from PyPI.**
 
-```bash
-pip install openmldb-exporter
-```
-
-Then type

-### Build python SDK (Optional)
+</details>
 
-openmldb exporter depends on [openmldb python SDK](https://pypi.org/project/openmldb/). For those introducing changes in python SDK or native code as well, this steps is required in order to take the latest Python SDK locally instead of the published one.
+## Configuration
 
-#### 1. Build native code
+You can view the help from:
+```sh
+openmldb-exporter -h
+```
+`--config.zk_root` and `--config.zk_path` are mandatory.
 
-`cd` to root directory of OpenMLDB, and run:
+<details><summary>Available options</summary>
 
-```bash
-make SQL_PYSDK_ENABLE=ON
+```
+usage: openmldb-exporter [-h] [--log.level LOG.LEVEL] [--web.listen-address WEB.LISTEN_ADDRESS]

+ --config.zk_root CONFIG.ZK_ROOT
+                       endpoint to zookeeper, default 127.0.0.1:6181
+ --config.zk_path CONFIG.ZK_PATH
+                       root path in zookeeper for OpenMLDB, default /
+ --config.interval CONFIG.INTERVAL
+                       interval in seconds to pull metrics periodically, default 30.0
 ```
 
-This will generate compiled shared library in `python` source directory.
+</details>
 
-#### 2. Fix dependency list
+## Development
 
-Back to openmldb exporter directory, modify `pyproject.toml` and make content like below:
+### Extra Requirements
 
-```toml
-[tool.poetry.dependencies]
-# ...
-# openmldb = "^0.6.0"
-# uncomment below to use openmldb sdk built from source
-# set develop = true so changes in python will take effect immediately
-openmldb = { path = "../python/", develop = true }
-```
+- Same in [Requirements](#requirements)
+- [poetry](https://github.com/python-poetry/poetry) as build tool
 
 ### Run
 
 1. Setup python dependencies:
 
-   ```bash
+   ```sh
    poetry install
    ```
 
 2. Start openmldb exporter
 
-   ```bash
+   ```sh
    poetry run openmldb-exporter
    ```
 
-   You need pass necessary flags after `openmldb-exporter`. Run `poetry run openmldb-exporter --help` to get the help info
-
-   ```bash
-   usage: openmldb-exporter [-h] [--log.level LOG.LEVEL] [--web.listen-address WEB.LISTEN_ADDRESS]
-                            [--web.telemetry-path WEB.TELEMETRY_PATH] [--config.zk_root CONFIG.ZK_ROOT]
-                            [--config.zk_path CONFIG.ZK_PATH] [--config.interval CONFIG.INTERVAL]
-   
-   OpenMLDB exporter
-   
-   optional arguments:
-     -h, --help            show this help message and exit
-     --log.level LOG.LEVEL
-                           config log level, default WARN
-     --web.listen-address WEB.LISTEN_ADDRESS
-                           process listen port, default 8000
-     --web.telemetry-path WEB.TELEMETRY_PATH
-                           Path under which to expose metrics, default metrics
-     --config.zk_root CONFIG.ZK_ROOT
-                           endpoint to zookeeper, default 127.0.0.1:6181
-     --config.zk_path CONFIG.ZK_PATH
-                           root path in zookeeper for OpenMLDB, default /
-     --config.interval CONFIG.INTERVAL
-                           interval in seconds to pull metrics periodically, default 30.0
-   ```
-
-3. View the available metrics, you can pull through `curl`
-
-   ```bash
-   curl http://127.0.0.1:8000/metrics
-   ```
+   Pass in necessary flags after `openmldb-exporter`. Run `poetry run openmldb-exporter --help` to get the help info.
