+# 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.

-Edit plugins/MobScores/config.yml to set scores per mob.
+MobScores awards ScoreKeeper points for configured mob kills. It is a Paper-only plugin for Paper 26.2 and 26.3, and requires the ScoreKeeper plugin to be installed and enabled first.
 
+## Requirements
+
+- Paper 26.2 or 26.3.
+- Java 25 to build the plugin.
+- ScoreKeeper 0.2.2 or newer.
+
+Install both plugin JARs in the server's `plugins` directory. MobScores declares ScoreKeeper as a hard dependency, so it will not enable without it. Bukkit and Spigot servers are not supported.
+
+## 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 Paper API `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. Entity type keys use the Paper API's `EntityType` names.
+
+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 go into ScoreKeeper's dedicated `mob-scores` bucket and are tracked by player UUID. Use `/score-bucket mob-scores` before `/score-get` to view mob points; MobScores does not change the player's active bucket automatically.
+
+## Build
+
+Run `./gradlew test` and `./gradlew build` from the project root. See [CONTRIBUTING.md](CONTRIBUTING.md) for toolchain, local server, and helper-script details.

+# MobScores Human Testing
+
+Use this checklist on a disposable Paper 26.2 or 26.3 server with Java 25+, MobScores, and ScoreKeeper 0.2.2 or newer installed. MobScores depends on ScoreKeeper for its `mob-scores` bucket, and its main behavior is driven by real combat and player-join events.
+
+## Test Setup
+
+- Back up the world and both plugin data folders. Configure a test server with the same plugin versions intended for production.
+- Use at least two ordinary player accounts and an operator for setup. Keep the server log visible to catch dependency, config, and offline-award warnings.
+- Save the generated `plugins/MobScores/config.yml` before changing it. Restart after config edits; MobScores reads the score table during plugin startup.
+- Record player UUIDs, mob types, configured values, active score buckets, and scores before and after each kill.
+
+## Human Checklist
+
+### Plugin loading and configuration
+
+- Start with both plugins installed. Confirm ScoreKeeper loads before MobScores, MobScores enables, and the `mob-scores` bucket exists with the expected labels and initial value.
+- On a disposable server, test startup without ScoreKeeper and with a ScoreKeeper version older than 0.2.2. Paper should reject the missing hard dependency; MobScores should disable itself with a version warning for an outdated dependency. Then restore the supported version.
+- On first startup, inspect the generated `ScoreTable`. Confirm the documented default entity values are present, including a zero-valued entry.
+- Change a few values, restart, and verify they are loaded and preserved. Include a zero value and an unknown entity key; confirm zero-valued entities are omitted from join messages and invalid entries are logged without preventing valid entries from loading.
+- Confirm the table uses Paper `EntityType` names and that malformed values or a missing score-table section are handled as intended.
+
+### Kill credit and scoring
+
+- As a player, kill configured entities using direct melee damage and player-fired projectiles. Confirm the expected points are added to that player's `mob-scores` score.
+- Check the boundary cases: a non-player attacker, environmental death, an entity type absent from the table, and a configured zero-point entity. Confirm no unintended points are awarded.
+- Have two players damage the same mob before it dies. The current implementation records the most recent direct or player-projectile attacker; verify that this credit policy matches the server's expectations.
+- Damage a mob with a player, then let it die from fall, fire, or another environmental cause. Confirm whether retaining that player's credit is the intended behavior; the current implementation keeps the last recorded player attribution until the mob dies.
+- Test a player who disconnects after damaging the mob but before it dies. The current implementation cannot award an offline player and logs a warning; confirm this is acceptable and that no other player's score changes.
+- Check mob death without any previous qualifying player damage, and verify no stale or reused entity attribution grants points.
+
+### Player messaging and ScoreKeeper workflows
+
+- Join with a player account. Confirm the MobScores score table is sent once, includes configured nonzero entity types with the right values, and excludes zero-valued types.
+- Run `/score-bucket mob-scores` followed by `/score-get`. Confirm the score reflects kills and the bucket switch message uses the expected singular/plural label. Verify MobScores does not change the player's active bucket automatically on join or kill.
+- Give two players different kill totals and switch between `mob-scores` and another ScoreKeeper bucket. Confirm each bucket retains its own value and MobScores awards only to `mob-scores`.
+- Restart the server and verify MobScores retains its configured table and ScoreKeeper retains the players' mob scores. Reconnect and confirm the join table still matches the active config.
+- Exercise normal gameplay around claimed mobs: unload/reload chunks, kill several entities rapidly, and test multiplayer combat. Watch for missed, duplicated, or cross-player awards.
+
+## Automated Coverage
+
+There are currently no Java test sources in MobScores and no `integrationTest` source set/task. Although Gradle declares JUnit, `./gradlew test` currently has no MobScores behavior tests. The testing tasks marked “Ready” in `TODO.md` have not been implemented. Build success alone does not verify real event attribution or compatibility with the installed ScoreKeeper jar.

+**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 26.2 or 26.3.
+- Java 25 or newer at runtime and for building.
+- ScoreKeeper 0.2.2 or newer.
+
+Install ScoreKeeper and MobScores in the server's `plugins` directory. ScoreKeeper is a required dependency and must be enabled for MobScores to load.
+
+MobScores targets Paper only; Bukkit and Spigot servers are not supported.
+
+## Configuration
+
+MobScores creates `plugins/MobScores/config.yml` from its defaults. Edit `ScoreTable` to configure point values by Paper API `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 the dedicated `mob-scores` ScoreKeeper bucket. Use `/score-bucket mob-scores` to view mob points with ScoreKeeper commands. 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 turns combat into a configurable scoring system. When a player damages a tracked mob, the plugin remembers the attribution and awards the matching ScoreKeeper bucket when that mob dies, including projectile kills.
+
+It is a deliberately small Paper integration plugin with a clear boundary: Paper entity events on one side, ScoreKeeper's public scoring API on the other. The per-entity score table is configurable, zero-value entries can be disabled, and players see the active mob-score table when they join. It targets Paper 26.2 and 26.3 only, not Bukkit or Spigot.
+
+## Engineering Notes
+
+- Built for modern Paper with Java 25 and Gradle.
+- Uses UUID-safe player attribution.
+- Depends on ScoreKeeper 0.2.2 or newer.
+- Tested through the standard server-free build workflow.
