Write a developer's guide

[ghost]

The developer's guide should integrate the already existing documentation with:

• Codebase Overview: Start with a high-level overview of your codebase. Describe the purpose of the library, its main features, and how it is structured at a high level. This includes the main modules, classes, and their relationships.

• Directory Structure: Provide a clear explanation of the directory structure of your codebase. This should include the purpose of each directory and the type of files that can be found in them.

• Key Components: Identify the key classes, functions, and modules in your codebase. For each of these, provide a brief description of its purpose, how it works, and how it interacts with other parts of the codebase.
