+# Creating a Module
+
+If you are interested in creating a module, this guide is for you. Note that you should be familiar with Java, Git, and
+the Gradle build system.
+
+## Cloning the template
+
+There is a template you can use when creating a module. You can find it on
+GitHub [here](https://github.com/plexusorg/ExampleModule). You should fork this onto your local GitHub account. You can
+then clone the fork to your computer. Once you have it open in your IDE, try building it with Gradle to ensure
+everything works.
+
+## Changing the branding
+
+In `settings.gradle.kts`, you should change the name to the name of the module you want. All modules follow the naming
+convention of `Module-<name>`.
+
+You should also open the `build.gradle.kts` file and change the description to `Module-<name>` as well. You should also
+change the version from `1.0` to the current version of Plex available. If you are building against `1.5-SNAPSHOT`, you
+should set your version to that as well.
+
+You should also look for this block of code in your `build.gradle.kts file`:
+
+```kts title=build.gradle.kts
+tasks.getByName<Jar>("jar") {
+    archiveBaseName.set("Module-ExampleModule")
+    archiveVersion.set("")
+}
+```
+
+Change the `Module-ExampleModule` to the name of your module. Ensure you keep the `Module-` part. This is the name of
+your JAR file. If you change it, the auto updater may not work.
+
+Finally, in `/src/main/resources/module.yml`, you should change this information to your liking. The version here should
+match the version you set in `build.gradle.kts`. The `main` property should be changed to the entrypoint for the module.
+This is very similar to the main JavaPlugin when creating a new Bukkit plugin.
+
+## Creating commands
+
+Commands are created just like they are in Plex. There is an example command to help you get started. It is a good
+template to follow, and you can customize it based on your needs. You are able to access all the APIs and data from
+Plex.
+
+When you create a new command, you should register it in your main class as follows
+
+```java
+registerCommand(new ExampleCommand());
+```
+
+Make sure you replace the `ExampleCommand` class with your own class that the command is in. You should have one
+`registerCommand();` call per class. Subcommands should be within each command class.
+
+You'll want to make sure your class extends `PlexCommand` and implements both the
+`execute(@NotNull CommandSender sender, @Nullable Player player, @NotNull String[] args)` and
+`smartTabComplete(@NotNull CommandSender sender, @NotNull String alias, @NotNull String[] args)` methods.
+
+You should implement the `@CommandParameters` and `@CommandPermissions` annotations instead of handling permissions for
+the main command inside of the actual `execute()` block.
+
+## Creating listeners
+
+Listeners function just like they do in Bukkit, they listen for events. You'll want to do two things. Make sure your
+listener extends the `PlexListener` class rather than the Bukkit default `Listener` class. The `PlexListener` class is a
+wrapper for the `Listener` class and has the same functionality as the Bukkit one. You'll also want to ensure you register the listener in the main class as follows:
+```java
+registerListener(new ExampleListener());
+```
+Make sure you replace the `ExampleListener` class with your own class name.
+
+You can listen for as many events as you like per class. An example to listen for an event when a player joins and send them a message is as follows:
+```java
+@EventHandler
+public void onPlayerJoin(PlayerJoinEvent event)
+{
+    Player player = event.getPlayer();
+    player.sendMessage(Component.text("This is a message from Plex's example module!").color(NamedTextColor.GOLD));
+}
+```
