+# README #
+# ------ #
+# #
+# ref is a plugin for storing HTML formatted references, mainly suited for programming. #
+# Your $REF_DIR variable is the directory for storing these references in. If it does not exist, it will be created automatically. #
+# Here is an example of what my $REF_DIR looks like, because this will be of use when I explain how your $REF_DIR has to be structured: #
+# #
+# ~/.ref/ #
+# ruby/ #
+# general/ #
+# index.html #
+# bash/ #
+# array/ #
+# index.html #
+# select/ #
+# index.html #
+# #
+# This is what the basic structure of your $REF_DIR should look like: Subdirectories for each subject, and then another set of subdirectories for the part of the #
+# subject you want to reference. And in the second subdirectory, an index.html file. #
+# #
+# I hope that you like this plugin and if you have any questions about it, send me (mrman208) a message on GitHub or email me at mrman208@me.com #
