Good try but please reverse all the changes you have made to the incode documents and the readme. I don't want those changes to be there.

[Labreo]

I don't want there to be anything to be added to the main readme. Please remove those changes.

Thanks for the feedback. I've reverted the README, in-code documentation, and architecture document changes as requested. I'll revise the contribution to focus only on the documentation areas you'd like improved.

Hi @Labreo,

I reviewed the latest documentation updates, including CONTEXT.md, CONTRIBUTING.md, and the current README.

Many of the architecture, workflow, and contributor-onboarding gaps I initially identified now appear to be covered by the recently added documentation.

Could you point me toward any specific areas that still need documentation improvements so I can focus my contribution on the remaining gaps instead of duplicating existing documentation?

Thanks!
