-## Introduction
-miniob设计的目标是让不熟悉数据库设计和实现的同学能够快速的了解与深入学习数据库内核，期望通过miniob相关训练之后，能够对各个数据库内核模块的功能与它们之间的关联有所了解，并能够在

+# Introduction
+miniob 是 OceanBase与华中科技大学联合开发的、面向"零"基础数据库内核知识同学的一门数据库实现入门教程实践工具。
+miniob设计的目标是让不熟悉数据库设计和实现的同学能够快速的了解与深入学习数据库内核，期望通过相关训练之后，能够对各个数据库内核模块的功能与它们之间的关联有所了解，并能够在
+使用数据库时，设计出高效的SQL。面向的对象主要是在校学生，并且诸多模块做了简化，比如不考虑并发操作。

 # How to build
-please refer to docs/how_to_build.md
+直接在本地搭建开发环境，可以参考 docs/how_to_build.md。
+
+# Docker
+
+首先要确保本地已经安装了Docker。
+
+- 使用 Dockerfile 构建
+
+Dockerfile: https://github.com/oceanbase/miniob/blob/main/Dockerfile
+
+```bash
+# build
+docker build -t miniob .
+docker run -d --name='miniob' miniob:lastest
+
+# 进入容器，开发调试
+docker exec -it miniob bash
+```
+
+- 使用docker hub 镜像运行
+
+```bash
+docker run oceanbase/miniob
+```
+
+Docker环境说明：
+docker基于`CentOS:7`制作。
+
+镜像包含：
+
+- jsoncpp
+- google test
+- libevent
+- flex
+- bison(3.7)
+- gcc/g++ (version=11)
+- miniob 源码(/root/source/miniob)
+
+docker中在/root/source/miniob目录下载了github的源码，可以根据个人需要，下载自己仓库的源代码，也可以直接使用git pull 拉取最新代码。
+/root/source/miniob/build.sh 提供了一个编译脚本，以DEBUG模式编译miniob。
