增加其他基础内容比如HTTP部分，如果方便的话增加应用相关书籍引用内容

- 增加其他基础内容。比如HTTP部分，HTTP应该也是比较重要但是项目中没有提到，比如HTTP的PUT/POST的区别
- 如果方便的话增加应用相关书籍引用内容。项目的内容精简概括的同时能不能大致介绍相关书籍的内容“深入理解Java虚拟机JVM高级特性与最佳实践”，“Java并发编程的艺术”，想深入理解可以看

Review the repository's existing documentation structure and identify where foundational topics and recommended reading are presented. Add a concise HTTP section covering PUT and POST differences, plus brief references to the named JVM and Java concurrency books. Done means both additions fit the project's concise style and the existing content remains consistent.
