+## Language customization
+
+All strings, even time units, are customizable. If you place a strings.yml file in the plugin folder, it will take
+priority over built-in languages. If you want to change strings, look at PermissionSigns/src/main/resources/strings.yml
+for the proper keys. All strings have the format: ENUM: "Displayed string". The enum must be identical as it defines
+which string you have changed. All strings belonging to a language are beneath the language code and indented with two
+spaces.
+
+The easiest way to add a new language is to copy an existing language and paste it into your custom strings.yml and
+change strings as necessary. If you don't include all strings, the remaining will use the built-in English translation.
+Remember to change the language code to whichever you use for your custom language.
