+	echo "	ref new topic subtopic"
+	echo "Where topic is the general topic, such as ruby. And subtopic is a more exact topic, like array."
+	echo "This will create a directory for the topic, and a subdirectory for the subtopic. You can then move a file of your desired format into the subtopic's directory."
+	echo
+	echo "To access your ref, you would do the following command: "
+	echo "	ref topic subtopic"
+	echo "Where topic and subtopic are the same as before, but ref will open the file under your topic/subtopic directory. Unless it is a full website."
+	echo
+	echo "You can also download full websites as a ref, as long as it has an index.html file, it will work."
