+# Placeholders API
+
+FancyCore includes a Placeholders API that allows you to create and manage custom placeholders for use in various plugins.
+
+## Parse placeholders
+
+To parse placeholders in a string, use the `PlaceholderService`'s `parse` method. Here's an example:
+
+```java
+PlaceholderService placeholderService = PlaceholderService.get();
+String parsedString = placeholderService.parse(player, "Hello, {player_name}! Your rank is {player_rank}.");
+```
+
+## Creating a custom placeholder
+
+To create a custom placeholder, implement the `PlaceholderProvider` interface and register it with the `PlaceholderService`. Here's an example of creating a simple placeholder that returns a player's rank:
+
+```java
+public class PlayerRankPlaceholder implements PlaceholderProvider {
+
+    @Override
+    public String getName() {
+        return "Player Rank Placeholder";
+    }
+
+    @Override
+    public String getIdentifier() {
+        return "player_rank";
+    }
+
+    @Override
+    public String parse(FancyPlayer player, String input) {
+        return player.getRank().getName();
+    }
+}
+```
+
+You can then register your placeholder provider with the `PlaceholderService`:
+
+```java
+PlaceholderService placeholderService = PlaceholderService.get();
+placeholderService.registerPlaceholderProvider(new PlayerRankPlaceholder());
+```
