+## Setup
+
+Building `python` bindings requires some extra setup.
+
+For small or first-time contributions, we recommend the dev container method. Prefer to do it yourself? That's fine too!
+
+### Using a dev container environment
+
+OpenDAL provides a pre-configured [dev container](https://containers.dev/) that could be used in [Github Codespaces](https://github.com/features/codespaces), [VSCode](https://code.visualstudio.com/), [JetBrains](https://www.jetbrains.com/remote-development/gateway/), [JuptyerLab](https://jupyterlab.readthedocs.io/en/stable/). Please pick up your favourite runtime environment.
+
+The fastest way is:

+
+### Bring your own toolbox
+
+The `python` binding requires `Python` to be built. We recommend using the latest stable version for development.
+
+Most operating systems and distributions already have Python installed. If not, please install Python and its development tools first.
+
+For Ubuntu and Debian:
+
+```shell
+sudo apt install -y python3-dev python3-pip python3-venv
+```
+
+## Prepare
+
+All operations were performed within a Python virtual environment (venv) to prevent conflicts with the system's Python environment or other project venvs.
+
+OpenDAL specify the `requires-python` in `pyproject.toml` as `>= 3.7`. You can use `python -m venv venv` to setup virtualenv to start development.
+
+After `venv` has been prepared, you can activate it by `source venv/bin/activate`.
+
+To simplify our work, we will utilize the tool [`maturin`](https://github.com/PyO3/maturin). Kindly install it beforehand.
+
+```shell
+pip install maturin[patchelf]
+```
+
+## Build
+
+To build python binding:
+
+```shell
+maturin develop
+```
+
+## Test
+
+OpenDAL adopts `behave` for behavior tests:
+
+```shell
+maturin develop -E test
+behave tests
+```
+
+## Docs
+
+Build API docs:
+
+```shell
+maturin develop -E docs
+pdoc opendal
