+reward for beating your own least time record, a record for beating the global least deaths record and a record for
+beating the global least time record. You can give an item, give money, give a permission or execute a console command
+with the winning player as an argument.
+
+Note, you can add as many rewards as you want for each reward condition, so you can add a permission and an amount of
+currency on the player's first win for example.

+## Record placeholders
+
+Player records can be displayed on a leaderboard by using PlaceholderAPI. If you want to display a sign-based
+leaderboard, you can use the [Placeholder Signs](https://git.knarcraft.net/EpicKnarvik97/PlaceholderSigns) plugin. The
+format for the built-in placeholders is as follows:
+
+`%gameMode_record_recordType_gameModeType_identifierType_identifier_recordPlacing_infoType%`
+
+| Variable       | Values                      | Description                                                                                                                        |
+|----------------|-----------------------------|------------------------------------------------------------------------------------------------------------------------------------|
+| gameMode       | dropper / parkour           | A selection of which game-mode you are getting a record for                                                                        |
+| record         |                             | This must be as-is. It's a selector in case placeholders are added for more than records.                                          |
+| recordType     | deaths / time               | Selects the type of record to get (deaths or time).                                                                                |
+| gameModeType   | default / inverted / random | Selects the game-mode to get the record for.                                                                                       |
+| identifierType | arena / group               | The type of thing the following identifier points to (an arena or an arena group).                                                 |
+| identifier     | ?                           | An identifier (the name or UUID) for an arena or a group (whichever was chosen as identifierType).                                 |
+| recordPlacing  | 1 / 2 / 3 / ...             | The position of the record to get (1 = first place, 2 = second place, etc.).                                                       |
+| infoType       | player / value / combined   | The type of info to get. Player gets the player name, Value gets the value of the achieved record. Combined gets "Player: Record". |
+
+## Notes about material tags
+
+Where a list of material is allowed, this plugin supports using material tags that specify a set of blocks. This makes
+it much easier to add a lot of blocks without ending up with hundreds of individual materials. To specify
+such a tag, use a `+` character, and then the tag name.
+See <a href="https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Tag.html">the documentation</a> for a complete overview
+of all tags. Only those with type `Tag<Material>` can be used.
+
+Example tags:
+
+- +WOOL
+- +WALL_SIGNS
+- +ACACIA_LOGS
+- +ALL_SIGNS
+- +DIAMOND_ORES
+- +DIRT
+- +DOORS
+- +DRAGON_IMMUNE
+- +FENCE_GATES
+- +FENCES
+
+## Language customization
+
+Most or all strings 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 MiniGames/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.
+
+The interval messages are unique in that if several values are separated by comma (option1,option2,option3), a random
+message will be chosen each time it's displayed.
