-This package is a re-implementation of the
-[MuJoCo physics engine](https://github.com/google-deepmind/mujoco) in
-[JAX](https://github.com/jax-ml/jax). This library is developed and maintained
-by Google DeepMind, and is kept up-to-date with the latest developments in
-MuJoCo itself.
+本软件包是基于 [JAX](https://github.com/jax-ml/jax) 对 [MuJoCo 物理引擎](https://github.com/google-deepmind/mujoco) 的重新实现。该库由 Google DeepMind 开发和维护，并与 MuJoCo 本身的最新进展保持同步。
 
-The `mujoco-mjx` package is API-compatible with MuJoCo, but is missing some
-features found in MuJoCo.  See our
-[documentation](https://mujoco.readthedocs.io/en/stable/mjx.html) for more
-details concerning feature parity.
+`mujoco-mjx` 软件包在 API 上与 MuJoCo 兼容，但缺少 MuJoCo 中的某些功能。有关功能特性的对齐情况，请参阅我们的[官方文档](https://mujoco.readthedocs.io/en/stable/mjx.html)。
 
-## Installation
+## 安装
 
-The recommended way to install this package is via [PyPI](https://pypi.org/project/mujoco-mjx/):

-We recommend going through the tutorial notebook which introduces the MJX API
-and trains a reinforcement learning policy in a few minutes: [![Open In
-Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/google-deepmind/mujoco/blob/main/mjx/tutorial.ipynb)
+我们建议查阅教程 Notebook，它介绍了 MJX API 并在数分钟内训练一个强化学习策略：

-## Versioning
+## 版本规范
 
-The `major.minor.micro` portion of the version number matches the version of
-MuJoCo that this library provides. Optionally, if we release updates to MJX that
-target the same version of MuJoCo, a `.postN` suffix is added, for example
-`3.0.1.post2` represents the second update to MJX for MuJoCo 3.0.1.
+版本号的 `major.minor.micro` 部分与该库所基于的 MuJoCo 版本保持一致。可选地，如果我们发布了针对同一 MuJoCo 版本的 MJX 自身更新，则会添加 `.postN` 后缀，例如 `3.0.1.post2` 表示针对 MuJoCo 3.0.1 的 MJX 第二次更新。
