+# PvP Kits Plugin for PaperMC 1.21.4
+
+A customizable PvP kit plugin with GUI selection and player-specific kit layouts.
+
+## Features
+
+- **GUI-based kit selection** - Inventory menu for choosing kits
+- **Persistent kit layouts** - Saves each player's item arrangement per kit
+- **Hardcoded default kits** - Pre-configured with balanced PvP loadouts
+- **Easy customization** - Simple to add new kits or modify existing ones
+- **Modern 1.21.4 support** - Includes all new weapons and items
+
+## Included Kits
+
+| Kit Name   | Icon Item | Special Features |
+|------------|-----------|------------------|
+| Warrior    | Diamond Sword | Diamond armor, strength effect |
+| Archer     | Bow       | Speed boost, arrows |
+| Tank       | Shield    | Damage resistance |
+| Assassin   | Netherite Sword | Speed/jump boost, ender pearls |
+| Mace       | Mace      | Wind Burst enchantment, netherite armor |
+
+## Commands
+
+- `/kits` - Open the kit selection GUI
+- `/kits save <kitname>` - Save your current inventory as a kit layout
+
+## Installation
+
+1. Download the latest `.jar` from Releases
+2. Place in your server's `plugins/` folder
+3. Restart your server
+
+## Configuration
+
+Kits are hardcoded in `KitManager.java`. To modify kits:
+
+1. Edit the `initializeKits()` method
+2. Rebuild the plugin (`gradlew build`)
+3. Replace the JAR file
+4. Restart server
+
+Example kit addition:
+```java
+Kit mage = new Kit("Mage", Material.BLAZE_ROD);
+mage.setHelmet(new ItemStack(Material.LEATHER_HELMET));
+// ... other armor/items ...
+kits.put("mage", mage);

+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
