JSQLParser is a great project, and I want to quickly familiarize myself with the source code and contribute to it. How should I get started? #2169

I have encountered some challenges in familiarizing myself with and understanding the JSQLParser source code. In order to familiarize myself with this project more efficiently and start development, I would like to ask the community the following questions:

• Do you have any recommended learning paths or resources to help me quickly understand the core architecture and implementation of JSQLParser?

• Are there any development documents or best practices that developers who want to expand their functionality can refer to?

• What process should I follow if I want to contribute some of my improvements or features to this project?

I am looking forward to extending JSQLParser and hoping to make some contributions to this project. Thank you very much for your help!
