+# WebGit
+
+A web interface for managing Git repositories, designed to work on retro systems
+such as Windows 3.11, Windows 98, and FreeDOS.
+
+## Overview
+
+WebGit allows old machines on a local network to interact with Git repositories
+through a simple HTML-based web interface. The server clones repositories to a
+shared network drive so that legacy systems can access the working files
+directly. Git operations — committing, branching, pushing, and pulling — are
+performed through the web UI since these machines cannot run Git themselves.
+
+```
+┌──────────────┐        ┌──────────────┐
+│  Win 3.11 /  │  HTTP  │              │    ┌────────────────┐
+│  Win 98 PC   ├───────►│   WebGit     ├───►│  Git remote    │
+│  (browser)   │        │   server     │    └────────────────┘
+└──────┬───────┘        └──────┬───────┘
+       │                       │
+       │    ┌──────────────┐   │
+       └───►│ Network drive│◄──┘
+            │ (work trees) │
+            └──────────────┘
+```
+
+## Features
+
+- **Clone repositories** — clone a remote repository; the working tree is placed
+  on the shared network drive and the `.git` directory is stored separately.
+- **Create commits** — stage files and create commits from the web interface.
+- **Push and pull** — sync with remote repositories.
+- **Branch management** — check out existing branches or create new ones.
+- **Retro-compatible UI** — pure HTML with table-based layout. No JavaScript or
+  CSS, so it works in period-appropriate browsers.
+- **Telnet interface** — planned interface for FreeDOS users without a graphical
+  web browser.
+
+## Tech Stack
+
+- Java 25
+- Spring Boot 4.0
+- Thymeleaf (server-side HTML templating)
+- Gradle
+
+## Configuration
+
+Configure the following properties in `application.properties` (or via
+environment variables / command-line arguments):
+
+| Property | Description |
+|---|---|
+| `webgit.worktree-path` | Path to the shared network drive where working trees are stored (the files your retro machines will access). |
+| `webgit.git-dir-path` | Path where `.git` directories are stored (can be a local disk on the server). |
+
+Example:
+
+```properties
+webgit.worktree-path=/mnt/shared/repos
+webgit.git-dir-path=/var/lib/webgit/git
+```
+
+## Building
+
+```sh
+./gradlew build
+```
+
+## Running
+
+```sh
+./gradlew bootRun
+```
+
+Then open `http://<server>:8080` in any web browser.
+
