+It’s important that you read this page and don’t just assume it’s okay to make changes to `inc/config.php`; it’s not. `inc/config.php` is used only to hold default values. It’s updated very frequently, so placing your local configuration there would make upgrading a very complicated process.
+
+Instead, edit `inc/instance-config.php`.
+
+# Config files
+
+Vichan is made up of multiple configuration files:
+
+*    `inc/config.php` — These are the defaults. Do not edit this file or you will have a very hard time upgrading in the future.
+*    `inc/instance-config.php` — Make all your site-wide changes here. This file is generated upon installation.
+*    `<board>/config.php` — Optional board-specific configuration files can also be made. These files don’t exist by default.
+
+The syntax for `inc/instance-config.php` and `<board>/config.php` is exactly the same to that of `inc/config.php`. You can copy lines from `config.php` and place them in either one of these config files. That is what `config.php` is for.
+
+The configuration variable (`$config`) is just one huge associative array, occasionally split into “sections”.
+Loading order
+
+It’s important to understand how the configuration files work to get the most out of Vichan.
+
+*    `inc/config.php` — $config is reset with the defaults.
+*    `inc/instance-config.php` — Some $config values are overwritten or changed.
+*    `<board>/config.php` — If it exists, some more $config values are overwritten.
+
+# Comments
+
+The comments in `inc/config.php` are probably the greatest source of documentation. It is filled with descriptions for specific config variables as well as examples, for you to copy into `inc/instance-config.php` and modify.
