confusing documentation about Development Process

[Costa Shulyupin]

There are five topics named "Development Process" or "Working with the
development community" or both.

It is clear that these topics are related to the development. Some
content is overlapping.

Questions:
- Is it by design or chance?
- What are the principal differences between the topics?
- Are there any outdated documents?
- How should it be?
