//This article is intended for wiki administrators.//
The main way to configure your Mycorrhiza instance is through the **configuration file**. It is located at the root of your wiki structure and is called `config.ini`.
The file is generated automatically when you create a new wiki:
* `WikiName`: //string//. The name your wiki has. It is shown in the header by default and in other places. **Default:** `Mycorrhiza Wiki`.
* `NaviTitleIcon`: //string//. The icon shown before the colon in the navigational titles above each hypha. You may want to use an emoji or HTML here. **Default:** `🍄` (mushroom emoji).
* `UseSiblingHyphaeSidebar`: //boolean//. Whether to show the [[/help/en/sibling_hyphae_section | sibling hyphae sidebar]]. You are discouraged from using the sibling hyphae sidebar on new wikis. Enable it on old wikis that depend on it heavily. **Default:** `false`.
* `UseAuth`: //boolean//. Whether to enable authorization system. **Default:** `false`.
* `AllowRegistration`: //boolean//. Whether you want unregistered visitors to be able to register themselves using the web form. **Default:** `false`.
* `RegistrationLimit`: //number//. There cannot be more registered users than this number. If the number is zero, there is no limit. Makes sense only when `UseRegistration` is `true`. **Default:** `0`.
* `Locked`: //boolean//. Whether the users have to authorize first to access the wiki. **Default:** `false`.
* `UseWhiteList`: //boolean//. Whether to use a whitelist to allow specific users in. **Default:** `false`.
* `WhiteList`: //list of strings//. Usernames of people to allow in, if `UseWhiteList` is turned on. **Default:** `[]`.
