README lacks basic project context and onboarding information

[xubinrui]

Problem statement

The repository currently exposes only a one-line README.md with the heading # test-code. There is no explanation of what the project does, why it exists, how to run it, or what a contributor or evaluator should expect to find in the repository.

Because the README is the first entry point on GitHub, this makes the repository difficult to understand without opening additional files, and in this case there are no other visible project files to provide that missing context.

Impact

• New visitors cannot quickly determine the purpose or status of the project.
• Contributors and reviewers do not have setup, usage, or validation guidance.
• The repository appears incomplete or abandoned even if work is intended to continue.
• Lack of context increases back-and-forth questions and slows onboarding.

Proposed fix

Expand README.md into a minimal project overview that includes:

• A short description of what test-code is for.
• The current project status (for example: experiment, template, work in progress, or production code).
• Basic setup or usage instructions, if any exist.
• A short repository structure section if more files will be added.
• Contribution guidance or a note that contributions are not yet open.

Suggested README outline:

1. Project summary
2. Purpose and scope
3. Setup / run instructions
4. Usage example
5. Project status
6. Contributing

Why this issue is worth addressing

Improving the README is a low-effort change with immediate payoff: it makes the repository understandable from the landing page, sets expectations for contributors, and gives the project a usable baseline for future development.
