+About
+========
+[Multiverse](https://dev.bukkit.org/projects/multiverse-core) was created at the dawn of Bukkit multiworld support. It has since then grown into a **complete world management solution!** Multiverse provides the easiest to use world management solution for your Minecraft server, big or small, and with great addons like [Portals](https://dev.bukkit.org/projects/multiverse-portals) and [NetherPortals](https://dev.bukkit.org/projects/multiverse-netherportals/), what's not to love!
+<br><br>
+Now it's time to create your very own Multiverse server, do check out our [Wiki](https://github.com/Multiverse/Multiverse-Core/wiki) and [Usage Guide](https://github.com/Multiverse/Multiverse-Core/wiki/Basics) to get started. Feel free to hop onto our [Discord](https://discord.gg/NZtfKky) if you have any question or just want to have a chat with us!
+
+### Amazing sub-modules available:
+* [Multiverse-NetherPortals](https://github.com/Multiverse/Multiverse-NetherPortals) -> Have separate nether and end worlds for each of your overworlds!
+* [Multiverse-Portals](https://github.com/Multiverse/Multiverse-Portals) -> Make custom portals to go to any destination!
+* [Multiverse-Inventories](https://github.com/Multiverse/Multiverse-Inventories) -> Have separated players stats and inventories per world or per group of worlds.
+* [Multiverse-SignPortals](https://github.com/Multiverse/Multiverse-SignPortals) -> Signs as teleprompters!
+

+#   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/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
