# Getting Started

This repository is a small Java codebase centered on source-file header patterns and documentation examples. There is no obvious runtime application or framework layer; instead, the value of the project is in the variety of file headers, license blocks, and change annotations used across a handful of simple classes.

## What This Project Does

The project demonstrates different ways Java source files can be documented: complete headers, partial headers, license notices, and files with no header at all. If you are new here, think of the repository as a set of reference examples for reading, comparing, and standardizing file-level documentation.

## Recommended Reading Order

1. `.codewiki/overview.md` — start with the repository summary to understand the purpose of the codebase.
2. `src/main/java/NoHeader.java` — read the simplest case first so you have a baseline.
3. `src/main/java/MitLicense.java` — compare a minimal license header against the no-header example.
4. `src/main/java/WithHeader.java` — review a concise, standardized header.
5. `src/main/java/Crosslink.java` — look at a class with inline add markers and a short versioned header.
6. `src/main/java/PartialHeader.java` — inspect an incomplete header and localized description.
7. `src/main/java/LongHeader.java` — finish with the most detailed revision history.

## Key Entry Points

There are no deeply connected classes or layered abstractions in this repository. The most useful entry points are the example classes themselves:

- [`NoHeader`](../src/main/java/NoHeader.java) — baseline class with no file-level comment.
- [`MitLicense`](../src/main/java/MitLicense.java) — example of a short license notice.
- [`WithHeader`](../src/main/java/WithHeader.java) — concise complete header.
- [`Crosslink`](../src/main/java/Crosslink.java) — header plus inline change markers.
- [`PartialHeader`](../src/main/java/PartialHeader.java) — partial header with a localized summary.
- [`LongHeader`](../src/main/java/LongHeader.java) — long revision-history header.

## Project Structure

The source tree is intentionally flat:

- `.codewiki/` — generated documentation for the repository.
- `src/main/java/` — the Java source examples.
- `src/main/java/*.java` — independent classes used to demonstrate header styles.

There are no visible submodules, service layers, or shared utility packages in the current tree. Each Java file stands on its own and can be read independently.

## Configuration

No application configuration files were detected in the current repository snapshot. That usually means there is nothing to configure for runtime behavior. If you are extending the project, look first for build files such as `pom.xml`, `build.gradle`, or tool-specific configuration in the repo root; none are present in the indexed tree shown here.

## Common Patterns

- **File-level headers are the main pattern.** Most examples begin with a structured comment block containing a title and version line.
- **Classes are minimal.** The Java types are intentionally small so the header format is easy to inspect.
- **Version markers are consistent.** Several files use the same `vXX.XX.XX` style and ticket-style annotations.
- **Inline change notes appear in `Crosslink`.** Look for `ADD START` / `ADD END` comments when you need an example of localized code changes.
- **Localized documentation appears in `PartialHeader`.** Some headers include Japanese text, so keep encoding and rendering in mind when editing.
- **The repository is documentation-first.** Most of the useful context is in comments and generated wiki pages, not in runtime code.

If you are trying to understand the codebase quickly, read the wiki overview first, then scan the example classes in the order above. That will give you the fastest mental model of how this repository is organized and what the headers are meant to illustrate.
