 ## Installation
 
 We strongly recommend our users to install PaddleSpeech in **Linux** with *python>=3.7* and *paddlepaddle>=2.3.1*.
-Up to now, **Linux** supports CLI for the all our tasks, **Mac OSX** and **Windows** only supports PaddleSpeech CLI for Audio Classification, Speech-to-Text and Text-to-Speech. To install `PaddleSpeech`, please see [installation](./docs/source/install.md).
+
+### **Dependency Introduction**
+
++ gcc >= 4.8.5
++ paddlepaddle >= 2.3.1
++ python >= 3.7
++ OS support:  Linux(recommend), Windows, Mac OSX
+
+PaddleSpeech depends on paddlepaddle. For installation, please refer to the official website of [paddlepaddle](https://www.paddlepaddle.org.cn/en) and choose according to your own machine. Here is an example of the cpu version.
+
+```bash
+pip install paddlepaddle -i https://mirror.baidu.com/pypi/simple
+```
+
+There are two quick installation methods for PaddleSpeech, one is pip installation, and the other is source code compilation (recommended).
+### pip install
+
+```shell
+pip install pytest-runner
+pip install paddlespeech
+```
+
+### source code compilation
+
+```shell
+git clone https://github.com/PaddlePaddle/PaddleSpeech.git
+cd PaddleSpeech
+pip install pytest-runner
+pip install .
+```
+
+For more installation problems, such as conda environment, librosa-dependent, gcc problems, kaldi installation, etc., you can refer to this [installation document](./docs/source/install.md). If you encounter problems during installation, you can leave a message on [#2150](https://github.com/PaddlePaddle/PaddleSpeech/issues/2150) and find related problems
