+If you have a feature suggestion for Multiverse-Core, read the following tips:
+
+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.
