Create 10 practical methods that developers can use to document their source code clearly, understandably, and maintainably in order to improve team collaboration and facilitate future maintenance.

Context: [Code documentation, developers, software development, maintainability, collaboration, comments, documentation standards, tools, code quality, clarity]

Goal: [Improvement of code quality through structured and comprehensible documentation, promotion of team communication, reduction of onboarding times and errors]

For each method explain:
1) a concrete technique or practice for code documentation (e.g. meaningful comments, documentation with tools like Javadoc or Sphinx, use of Readme files)
2) examples from different programming languages or project types
3) tips for integration into the development process and for avoiding common mistakes

The methods should:
- be easy to understand and practice-oriented
- be suitable for both beginners and experienced developers
- contribute to the sustainable improvement of code readability and maintainability
- promote collaboration within the developer team
