+INTRODUCTION
+-------------------------------------------------------------------------------
+This document covers basic upgrade notes for major ENiGMA½.
+
+
+BEFORE UPGRADING
+-------------------------------------------------------------------------------
+* Always back ALL files in the 'db' directory
+* Back up your menu.hjson (or renamed equivalent)
+
+
+GENERAL NOTES
+-------------------------------------------------------------------------------
+Upgrades often come with changes to the default menu.hjson. It is wise to 
+use a *different* file name for your BBS's version of this file and point to
+it via config.hjson. For example:
+
+general: {
+	menuFile: my_bbs.hjson
+}
+
+After updating code, use a program such as DiffMerge to merge in updates to
+my_bbs.hjson from the shipping menu.hjson.
+
+
+FROM GITHUB

+

+	npm install

+PROBLEMS

+	If you have overridden or made additions to archivers in your config.hjson
