+# HUSH3.conf config options
+
+This document explains all options that can be used in HUSH3.conf
+
+# Basics
+
+Options can either be put in HUSH3.conf or given on the `hushd` commandline when starting. If you think you will want to continually use a feature, it's better to put it in HUSH3.conf. If you don't, and start `hushd` without an option on accident, it cause a downtime from a long rescan, that you didn't want to do anyway.
+
+
+# rescan=1
+
+Defaults to 0. Performs a full rescan of all of chain history. Can take a very long time. Speed this up with `rescanheight=123` to only rescan from a certain block height. Also speed this up with `keepnotewitnesscache=1` to not rebuild the zaddr witness cache.
+
+# txindex=1
+
+Defaults to 1. This is a default option that should not be changed or things will not work correctly.
+
+# zindex=1
+
+Defaults to 0. This option enables the "shielded index" which also calculates the "anonset" (anonymity set) also known as the "shielded pool". This data is avaailable in the getchaintxstats RPC, if zindex is enabled.
