-1.  Fill out the template.
-      This will help us understand what you're requesting and why you want us
-      to add it.
-
-2.  Keep it simple.
-      Make sure it's easy to understand what you're requesting. A good way is
-      to keep it to one request per GitHub issue, as we can then easily track
-      feature requests.
-
-3.  Check whether it has already been asked or added.
-      You can search the issue tracker to see if your feature has already been
-      requested at https://github.com/Multiverse/Multiverse-Core/issues.
-
-4.  Ask yourself: "Does this belong in Multiverse-Core?"
-      There are lots of features that we reject because most servers won't
-      need or use them. If your feature is very specific or already exists in
-      another plugin, it might not be a good fit for Multiverse-Core.

+# About
 
-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!

+#       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
