+# Contributing
+
+## Requirements
+
+- Java 25. The Gradle toolchain can download it automatically; `tools/build-plugin.sh` also provisions Temurin 25 under the project Gradle user home.
+- A recent Paper server for runtime testing.
+- The ScoreKeeper plugin, which is a required runtime dependency.
+
+## Build and Test
+
+From the project root:
+
+```sh
+./gradlew test
+./gradlew build
+```
+
+The distributable plugin JAR is written to `build/libs/`. To use the repository helper, run:
+
+```sh
+tools/build-plugin.sh
+```
+
+## Local Paper Testing
+
+Set `PAPER_VERSION` and `MINECRAFT_SERVER_PATH` in a local `.env` file at the MobScores project root, or export them in your shell. Set `MINECRAFT_ENV_FILE` if the helper scripts should load a shared environment file instead. Build ScoreKeeper and install it into the server first, then build and deploy MobScores:
+
+```sh
+tools/build-plugin.sh
+tools/deploy-plugin.sh
+```
+
+Start the server with `tools/start-server.sh`. The script downloads a stable Paper build when one is not already present. Review the server log for dependency and plugin-load errors, then test score-table configuration and mob-kill scoring in game. Back up the server before testing against a world with data you care about.
+
+## Configuration
+
+The default resource is `src/main/resources/config.yml`; Paper copies it to `plugins/MobScores/config.yml` on first startup. `ScoreTable` maps Bukkit `EntityType` names to integer point values. To change values on a test server, edit the generated config and restart the server.
+
+## Helper Scripts
+
+- `tools/build-plugin.sh` builds with Java 25.
+- `tools/deploy-plugin.sh` copies the latest non-`-all` JAR into `$MINECRAFT_SERVER_PATH/plugins/`.
+- `tools/start-server.sh` downloads/resolves and launches Paper using `.env` settings.
+- `tools/backup-server.sh` and `tools/restore-server.sh` manage server backups.
+- `tools/publish-local.sh` publishes the artifact to Maven Local for dependent plugin builds.

+**MobScores**
+
+MobScores awards ScoreKeeper points for configured mob kills. Set a score for each supported entity type and let ScoreKeeper track the player's total by UUID.
+
+## Requirements
+
+- Paper 1.21.7 or a compatible newer server.
+- Java 25 or newer at runtime and for building.
+- ScoreKeeper 0.2.2 or a compatible release.
+
+Install ScoreKeeper and MobScores in the server's `plugins` directory. ScoreKeeper is a required dependency and must be enabled for MobScores to load.
+
+## Configuration
+
+MobScores creates `plugins/MobScores/config.yml` from its defaults. Edit `ScoreTable` to configure point values by Bukkit `EntityType` name:
+
+```yaml
+ScoreTable:
+  ZOMBIE: 25
+  CREEPER: 50
+  SILVERFISH: 0
+```
+
+Set an entity's value to `0` to disable its points and hide it from the join-time score table. Restart the server after changing the configuration.
+
+## Scoring
+
+MobScores records credit for configured entity types damaged directly by a player or by a projectile fired by a player. When a credited player remains online when the entity dies, its configured points are added to that player's active ScoreKeeper bucket. Other mob attribution is not currently handled.
+
+MobScores has no commands of its own. Players see the nonzero score table when they join.
+
+## Build
+
+Run `./gradlew test` and `./gradlew build` from the project root. See [CONTRIBUTING.md](CONTRIBUTING.md) for development and local Paper testing instructions.

+# MobScores
+
+MobScores is a legacy Bukkit plugin that awards configurable scores to players for killing mobs. It works with the `ScoreKeeper` plugin, records the player who last damaged a mob, and awards the configured value when that mob dies.
+
+## Details
+
+- Platform: Bukkit/Minecraft server plugin
+- Language: Java
+- Dependency: ScoreKeeper
+- Configuration: `plugins/MobScores/config.yml`
+- Commands: None
+- License: GNU Affero General Public License v3

+# MobScores
 
-No Commands
+MobScores awards ScoreKeeper points for configured mob kills. It is a Paper plugin and requires the ScoreKeeper plugin to be installed and enabled first.
 
-Edit plugins/MobScores/config.yml to set scores per mob.
+## Requirements
 
+- Paper 1.21.7 or a compatible newer server.
+- Java 25 to build the plugin.
+- ScoreKeeper 0.2.2 or the version declared by `build.gradle`.
+
+Install both plugin JARs in the server's `plugins` directory. MobScores declares ScoreKeeper as a hard dependency, so it will not enable without it.
+
+## Score Table
+
+On first startup, MobScores creates `plugins/MobScores/config.yml` with default scores for supported entity types. Edit the `ScoreTable` mapping to change points; keys are Bukkit `EntityType` names and values are integer points:
+
+```yaml
+ScoreTable:
+  ZOMBIE: 25
+  CREEPER: 50
+  SILVERFISH: 0
+```
+
+Restart the server after editing the configuration. A configured value of `0` suppresses that entity from the score table shown to players when they join.
+
+MobScores has no commands of its own. It records credit for configured entity types damaged directly by a player or by a projectile fired by a player. Other mob attribution is not currently handled. Points are awarded through ScoreKeeper's existing player API and follow the player's UUID-backed score.
+
+## Build
+
+Run `./gradlew test` and `./gradlew build` from the project root. See [CONTRIBUTING.md](CONTRIBUTING.md) for toolchain, local server, and helper-script details.

 # Modernize MobScores Plugin: Implementation Tasks
 
-- [x] Analyze all Java source files for deprecated or removed Bukkit API usage, including logger, event registration, listener classes, configuration API, and entity/player mapping.
-- [x] Identify and document any hardcoded Bukkit references or legacy patterns (e.g., Player as HashMap key, old event registration, CraftBukkit class names).
-- [ ] Review and list any custom scripts or resources (e.g., bash scripts in tools/bash/) that may need migration or updates.
-- [x] Initialize Gradle in the project root and create a build.gradle file with project metadata, PaperMC API dependency, JUnit, Java toolchain, repository, resource handling, and plugins as needed.
-- [x] Remove Maven-specific files (pom.xml, .mvn/ directory, Maven wrapper scripts) and Eclipse-specific files (.classpath, .project, .settings/) if present.
-- [x] Update .gitignore to add Gradle-specific ignores and remove Maven/Eclipse-specific ignores.
-- [x] Ensure plugin.yml is present in src/main/resources and update for PaperMC compatibility (api-version, commands, required fields).
-- [x] Refactor all logger usage to use getLogger() from JavaPlugin.
-- [x] Refactor all event listeners to use the modern event system (Listener interface, @EventHandler, registerEvents).
-- [x] Replace use of org.bukkit.util.config.Configuration with the modern configuration API (getConfig(), saveConfig(), etc.).
-- [x] Update score table to use Bukkit entity types or enums instead of CraftBukkit class names.
-- [ ] If storing player scores, refactor to use UUID as the key instead of Player or String.
-- [x] Build the plugin with Gradle (./gradlew build) and test on a modern Paper server using the provided bash scripts.
-- [x] Address any bugs or incompatibilities found during testing on a modern server.
-- [ ] Update README.md and CONTRIBUTING.md with new build, usage, and development instructions. _(Depends on: bugfixes)_
-- [ ] (Optional) Add new features, quality-of-life improvements, automated tests, or CI configuration. _(Depends on: docs update)_
-- [x] Update MobScores to depend on the latest version of the ScoreKeeper plugin (update dependency in build.gradle and plugin.yml as needed).
-- [ ] Test MobScores with the latest ScoreKeeper to ensure score tracking, awarding, and all integration points work as expected (including with players who have changed names).
-- [x] Refactor MobDeathListener and PlayerConnectListener to implement Listener interface and use @EventHandler annotations instead of extending EntityListener/PlayerListener.
-- [x] Update event registration in MobScoresPlugin to use getServer().getPluginManager().registerEvents(...).
-- [x] Replace all usage of org.bukkit.util.config.Configuration with the modern Bukkit configuration API (getConfig(), saveConfig(), reloadConfig(), etc.).
-- [x] Remove or refactor any code using deprecated or removed Bukkit/Spigot/Paper APIs that are not available in the modern Paper API.
