+# Simple Player List
+
+Simple Player List is a **server-side** mod which introduces the ability to customize server's player list through a
+configuration file.
+
+## Features
+
+- Modify the player list appearance using a JSON configuration file.
+- Show real-time server statistics directly in the player list.
+
+## Configuration
+
+Upon loading the mod for the first time, a default configuration file will be generated
+(`config/simpleplayerlist.json`):
+
+```json
+{
+  "enable_mod": true,
+  "header": "§lDefault Config§r\n\n§7To change this, edit\nconfig/simpleplayerlist.json\n\n§r§b§m                                        §r",
+  "footer": "§r§b§m                                        §r\n\n§7TPS: %tps%§7/%mspt% §8-§7 Ping: %ping%\n§7Day: §b%day%",
+  "tick_update_interval": 20
+}
+```
+
+This file supports the [§-based formatting system](https://minecraft.wiki/w/Formatting_codes) and hex colors
+(e.g., `§#FFFFFF`).
+
+The following placeholders will be dynamically replaced with real-time server information at the interval specified by
+`tick_update_interval`:
+
+- `%mspt%`: Displays server the server's MSPT (Milliseconds Per Tick).
+- `%tps%`: Displays the server's TPS (Ticks Per Second).
+- `%ping%`: Shows the player's ping in milliseconds.
+- `%day%`: Indicates the current in-game day.
+
+`%mspt%`, `%tps%` and `%ping%` are heatmap colored for easier interpretation.
+
+## Commands
+
+To apply changes made to the configuration file, you can use the in-game command `/playerlist reload`. You can also
+enable or disable the mod with `/playerlist toggle`.
+
+Players without operator status can run `/playerlist` to toggle the mod on their end.
+
+## Support and Contributions
+
+Feel free to report issues or suggest features through the mod's issue tracker. Contributions are welcome - simply fork
+the repository and submit a pull request with your improvements.
+
+---
+
+[Fabric API](https://modrinth.com/mod/fabric-api) is required to run this mod.

+#   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.
