+
+---
+
+<!-- EssentialsX feature request guide
+
+Fill out the template. Don't write inside the arrows as they will be hidden
+when you post your issue.
+
+Not sure if your feature fits in EssentialsX? Feel free to ask on our Discord
+server: https://discord.gg/F7gexAQ
+
+If you have a feature suggestion for EssentialsX, 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/EssentialsX/Essentials/issues. You can
+      also check the wiki at https://essentialsx.github.io/ to see if the
+      feature was recently added.
+
+4.  Ask yourself: "Does this belong in EssentialsX?"
+      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 EssentialsX.
