+# 🛠️ Creating a Command
+
+Commands are a core feature of Discord Bots. They allow users to interact with the bot and perform various actions. In MoBot, creating a command is straightforward and flexible, allowing you to define custom behavior for your bot.
+
+## 🚀 Commands in the MoBot API
+To make commands easy to use, MoBot provides a extensive API for creating and managing commands. 
+Apart from the `SlashCommandHandler` interface, the SlashCommand System is build entirely from annotations.
+
+::: warning NOTE
+You will have to implement the `SlashCommandHandler` interface if you want to use `@SlashCommand` and other annotations.
+:::
+
+## 📜 `@SlashCommand` Annotation
+The `@SlashCommand` annotation is used to define a slash command. Apart from the name and description, you can also specify aliases and required permissions.
+This annotation is placed on a method that will handle the command when it is invoked. 
+The method should accept a `SlashCommandInteractionEvent` parameter, which contains information about the command invocation and allows you to respond to the user.
+
+| Option          | Description                                                                  |
+|-----------------|------------------------------------------------------------------------------|
+| `name`          | The name of the command. This is what users will type to invoke the command. |
+| `description`   | A short description of what the command does.                                |
+| `aliases`       | An array of alternative names for the command.                               |
+| `permissions`   | The permission required to use the command.                                  |
+
+Here’s an example of a simple `PingCommand` using the `@SlashCommand` annotation:
+
+```java
+public class PingCommand implements SlashCommandHandler {
+    @SlashCommand(
+        name = "ping",
+        description = "Ping the bot to check if it's alive"
+    )
+    public void onPingCommand(SlashCommandInteractionEvent event) {
+        event.reply("Pong!").queue();
+    }
+}
+```
+
+## 🛠️ Registering the Command
+
+To register the command, you need to create an instance of your command class and register it using the `#registerSlashCommandHandler` method in your module's main class.
+
+Here's an example of how to register the `PingCommand` in your module:
+
+```java
+public class MyModule extends MbModule {
+    @Override
+    public void onEnable() {
+        registerSlashCommandHandler(new PingCommand());
+    }
+}
+```
