+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
-
-[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!
-
-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 teleporters!
-
-## Building
-Simply build the source with Gradle:
-```
-./gradlew build
-```
 More details are available on the [build instructions wiki page](https://github.com/Multiverse/Multiverse-Core/wiki/Building).

-#   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.
