-Hello! This is your new wiki directory. It contains various files that control
-how wiki looks and works. Here's a brief breakdown of them.
-
-wiki.git/
-    This is a Git repository that holds all of your wiki's content. If you want
-    to manually change something, add or remove files, do it there. Everything
-    inside is publicly accessible, so don't place something private in there.
-
-static/
-    This directory can be used to serve additional static files, or to overwrite
-    built-in ones. Here are some of the files you might want to place here:
-        common.css:     replaces Mycorrhiza Wiki's default stylesheet
-        custom.css:     adds additional styles to common.css
-        favicon.ico:    sets the website favicon
-
-cache/
-    This directory contains temporary files such as user tokens. You can
-    safely delete this directory, and nothing will break.
-
-README.txt
-    We're here! Feel free to remove this file if you don't need it.
-
-config.ini
-    This is the main configuration file that holds all your wiki's settings,
-    such as it's name, special hyphae, network configuration and, optionally,
-    additional JavaScripts.
-
-fixed-users.json
-    This file holds all fixed users' credentials. Not recommended to use.
-    See https://mycorrhiza.wiki/hypha/feature/authorization/fixed.
-
-registered-users.json
-    This file holds all registered users' credentials, securely hashed and
-    protected. This file is updated automatically, and you're discouraged from
-    editing it by yourself. More user control features are coming in the future.
