-TODO
+本仓库为少数派平台 [《100 小时后请叫我程序员》](https://sspai.com/series/271) 教程内容的相关源码、以及素材仓库，教程内的大部分示例代码都可通过对应的目录找到。
 
-# 环境依赖安装
+在使用过程中如有任何问题欢迎在少数派私信我（推荐方式），或者在本仓库上面的 Issues 页面中提问。
 
-TODO
+在使用前需要将本仓库的项目下载后再通过 IDE 打开。
 
-# 项目使用
+## 环境依赖安装
 
-TODO
+参照教程内容安装好 Python 解释器、镜像配置以及设置相关的 IDE 之后，进入到该项目路径下，使用对应 Python 解释器的 `pip` 命令来进行安装 `requirements.txt` 文件中的依赖。
 
-# LICENSE
+### 查看当前 Python 解释器路径
 
-TODO
+Windows：
+
+```powershell
+where.exe python3
+# or where.exe python
+```
+
+macOS：
+
+```bash
+which python3
+# or which python
+```
+
+### 运行 pip 命令
+
+方式一（推荐）：通过指定 Python 解释器来运行
+
+```bash
+cd ./sspai-100-hours-series-python
+python3 -m pip install -r ./requirement.txt
+```
+
+方式二：
+
+```bash
+pip install -r ./requirement.txt
+```
+
+## 项目使用
+
+教程内容中所涉及到的 `.ipynb` 结尾的 Notebook 文件需要通过 Jupyter Notebook 打开，即在当前目录下运行如下代码启动 Jupyter 服务，然后在当中以 REPL 方式使用：
+
+```bash
+cd ./sspai-100-hours-series-python
+python3 -m jupyter notebook .
+# or jupyter notebook .
+```
+
+除此之外，如果是以 `.py` 结尾的 Python 代码文件，则可以直接通过 IDE 进行运行。
